Thanks for Revisiting. Using your Method will get one close. Helpful if you just need to know where to look for the Actual Pins. An inexpensive Metal Detector can also be useful to sweep around the GPS area to find the Actual Pins.
At some point, at least for residential properties, there would have been survey pegs that are likely still buried just below the surface. The APPROXIMATE locations you identify in your videos are where a metal detector should then be used to locate the original nailed or metal survey pegs. The greatest errors in the app based locating approach you describe are the hardware limitations of the phone or tablet GPS system, which are more significant for small residential properties than the 2D/3D geometry mismatch.
For my subscribers reading comments........This guy wants you to spend $1,200 or $2,000 to get your property Surveyed before even trying other solutions that can range from $5 to $8.
@@MarkTheRealtor you are going to cost people a lot of money surveys get you within .5 inches. If you rely on 3 FEET accuracy, you could be in a lot of expensive trouble.
@@edwardfisher2787 Edward, I have coached 1,000's of home owners to find their properties either EXACTLY, or within inches of exact.

Amazing Stuff! I am his brother and also an engineer. I did not know any of this, and I will bet that the percentage of realtors who know this cannot be measured with the 6 digits after the decimal point! Imagine what he can tell you about your home construction and the process of buying a house!
Those 14", 32", 31" variances can get you sued and lose in court where you may have to pay your own legal fees, the court costs, and the other guys court costs. Get some quotes and get a real surveyor. I wouldn't depend on a geolocation mapping app. Satellites are off
For viewers reading comments, the solution you will see over and over again is to pay $1,300 or $2,500 for a Survey. Legally Survey's are supposed to be the most accurate, but I have had Survey's done where there was over 100' of inaccuracy. With the video's on my channel you have more tools to use now.
super overview and exactly what I was looking for and appreciate the education on the accuracy and options available - just beginning to delve into the options out there and if I really need to hire a pro or can get close enough with what I am planning with my backyard.
Thanks for the not DO. Also on my Channel are 15 Use Cases that discuss when important Survey's are recommended and sometimes when they are not. My neighbor wanted to build a swing set near his back property line, and he felt like getting a $1,200 survey for that use case was not needed.
I suggest people buy those laser distance measure devices, $20-40 each. They measure 50-120 meters, and I've seen 150 meter and even 200 meter measure units. Sadly, I haven't seen an equivalently cheap angle measure device, a theodolite, or a way to make a total station. Sure, a professional surveyor would call this a 'toy', but technology advances by providing older technology at lower prices than before.
Hi Mark. Very interesting video. Many thanks. I have now used Google Earth to plot a rectangular area in a field. I have the coordinates... however, what app are you using to enter the coordinates so that when you go into the field you can walk to the "exact" spot? In your video there appears to be a map with a clinometer overlay. What App is that (and how do you get that "view"?
Hi Mark. Okay, good work. The App I use to walk to Latitude and Longitude dots is Coordinates Plus by Mapnitude. It has been a huge help. Also, GoogleMaps can work if you enter the coordinates in the search bar where normally an address would go.
This method helped me locate a property stake, buried in a densely wooded area. Got within 5' using a Garmin Foretrex 601. But when the trees leafed out it became impossible to return to the same location. The limited number of satellite signals was the cause.
All helpful but 23 inches is 23 inches. In fact, one inch is one inch. My very good neighbor is a little concerned about the property line and I want to be agreeable with him as much as I possibly can. I am certain where one property line is in the front. I used to be certain where the opposite front line is but can no longer find the marker that was there but I know the edge of the walk was placed on the marker. Both of us have a desire to be liberal with the rear property lines that are on a golf course. I think the rear marking were covered up by the third party. If one of the trees planted there falls over fifty years from now it could be a problem. But, it won't be my problem because I won't be here to see it. I think I'll check with the county and see what they have to say. I have a free app on my phone called GPS tools. It is helpful in so many ways but I need those coordinates to do the job. Right now I have 37 satellites I can count from inside my house. I can clearly see their coverage and quality. My altitude is 1001 feet and I am at xx degrees 5x'29.161'W. I think I need more accuracy on those last 3 numbers.
minimg claims are located with a discovery post and corner posts that are all determined from the location of the first post, i.e. post #1 by township, range, section and sometimes divisions of the section, se nw etc. then post #2 is X number feet in the direction from the first post. post #3 and #4 follows suit. no gps coordinates are marked. lots of inaccuracies and no updates on the location method. However the BLM uses gps machines that are very accurate to record where the digging on the claim is to happen. They don't tell you those exact coordinates...maybe you have to ask for them? So a miner could be digging out of bounds and not know it.
Mark apology for the weird ask - but I've been trying to get hold of an inflatable globe like yours in that size for months! Any links? Much appreciated. Really learned a lot from your video, didn't realise what could be done with existing software.
Hi Dan. Sure, no problem. I found mine on Amazon and have used it so many times. Search "Huge Inflatable Globe, 1 Meter in Diameter, Earthball". The volume is so vast, consider going to a gas station and using there tire inflation pump.
I paused to see if I would have to sign in.. One of several Geometric aspects you did not mention and this one should be is the Satelite positiona relative to your Phone. Your Phone (Receiver) was held or mounted on a Pedistal. This adds around a yard above the spot you marked. Satelites are usually anywhere from 10 to 90 deg abobe the Horizon in any direction incurring a significant paralax error. This should be considered in your calculations. I guess for best relative accuracy your Phone would have to be on the Ground. thanx jw K5JDW
Hi John. It's a pedestal. And it was about 40" off the ground. During the readings there were 12 or more satellites tracking the location at all times. The parallax to which you are referring over that 40" of height may have caused the measurement to be off 0.00001 meters which is roughly the width of a human hair. I'm not putting the Garmin or my Phone on the ground for that type of tolerance.
This is ok getting ideas of the corner are. There's a lot of misinformation. The gps in-accuracy is on the receiving end, antenna and app resolutions, not that we live on a globe.
Hi R. For most of my adult life GPS accuracy was a real issue. The GPS chips are so much better now. When I go outside with my Garmin devices they detect between 12-18 satellites at the same time and triangulate between all of them. THAT is one reason why they are much more accurate than in 2015. Technology wins.
Ok here is something to be careful of. Those pretty lines put on GIS maps aren’t the legal property lines. They are put in many times by summer help and interns Frequently they missing offsets and angles I’ve run into a number of situations where this has happened and do have other surveyors So if you want to do it right you have to go off the actual coordinates those are what are actually recorded on plats The lines are for people scanning property on maps to get a good feel of the boundaries
The difference between Survey accuracy and GPS phone accuracy is clearly shown on most of my video's. On video and on spreadsheets. When you say it isn't accurate enough. May I ask, for who?
My neighbor has replaced the original metal markers with his own 8-10” nails by hammering them in the posts of my fence. The original metal pins were in the former fence, that he took out. How can I find the exact measurements without using metal pins? Do surveyors always use metal markers, or is it possible to physically measure from the corner lot along the street to each house?
This does sound like a Licensed Surveyor needs to come in and figure it out. They have the equipment and expertise to be precise. Sorry this is happening to you.
Hi Joe. Over 100 experts have told me the 15' cushion and now measuring over 200 properties, I have not found that to be true. At least in my part of Missouri, when I slow down, let the devices acclimate with 15 satellites connected, they are almost always within 3' of actual survey stakes.
As magnetic north wanders around. Many old surveys "set" the basic plan.. Just try and undo a 100 year old map...I have seen graveyards start hatfield / mcCoy wars and no one wins.
I live in a remote location on a mountain. Lousy Internet and no cell reception. What can be done. OnX can give me the boundary lines but no tracking. In Oregon in the Willamette valley.
Hi Russ. Thanks for the note. Does your County have the parcels mapped accurately? IF so perhaps you could get the Lat/Long Coordinates off your County site? And then in hilly areas I would recommend a Garmin type of handheld that can triangulate off of 10+ satellites at once.
If you are on a ball, everybody in Australia would be upside down. It is really that simple, and the complicated explanation provided to excuse the obvious is so insane. Of course this place is not literally flat though it is an extended plane of varying heights.

@cbdyna because you are not within the functional footprint of the correct signal Tx/Rx. Remove your tinfoil/aluminum foil hat and do some research. All the answers are at your finger tip, just be prepared to research the research!

I understand exactly what you are saying however I don’t think we can locate our properties exactly by using GPS numbers. From what I understand, our government messes with the settings so they aren’t always exact. If they don’t want you to find an exact point, they can adjust the settings so they are not accurate, well at least that’s what I’ve always been told. Somebody please correct me if I’m wrong. Thank you.
Thanks for weighing in Frank. Yes, I too have heard that intentional bias is added. In measuring dozens of properties I own or have under contract the accuracy is rarely outside of 5' and usually within 3'. Many of my parcels have had a survey prior, but the pins have been covered over the years.
Until 2000 something called S/A, or selective availability was used to deaccurize GPS but that was ended. For a long while smartphones used GPS that was commonly reference to be 10 meters accurate, though it was probably more like 5 meters. Recently smartphones have been built that have something called dual frequency GPS and sbas corrections. If your phone has both, the accuracy approaches 1 meter. If you're willing to spend about $600, you can get a GPS receiver with an accuracy of about 10 millimeters, a technique called RTK. But you will have a lot of learning to do. Even then, the problem is that most survey drawings don't even reference latitude and longitude: they reference distances to stakes in the neighborhood.
Yes, thank you for the note. Yes it is widely understood that Survey's are more accurate. AND, we all know many will not pay the $600 or $1,200 to survey even a small parcel.
With the current technology available to the public, I think this is the best we can do. Surveyor's have more expensive equipment and can get very accurate.
When I used Google Earth and Parlay I get this image showing property lines running through my house and houses in my neighborhood. Any way to correct? I also checked municipal maps and see the same error.
That’s because GIS uses tax maps. Tax maps only show the property lines approximately. When you open up your local GIS it probably has a disclaimer explaining that GIS is not exact.
As a title company owner we find surveying mistakes all the time. They get testy when a title company calls them and informs them that the legal description they wrote is wrong. Title companies insure these properties and are liable for the accuracy of what we put in the title policies. The surveyor can be held liable also.
Great points. I order and pay for 60 Survey's a year and 10% of them are wrong. Often they are dead wrong. And the surveyors do enjoy saying the Title is dysfunctional. Sometimes, not always, they're right.
This guy is dangerous. Misleading information is worse than no information. What good is a DIY survey that is only accurate to 4 ft. A professional survey is good for 1:10,000, or 1/8th of an inch. Yea, it's expensive but so is the equipment to produce the accuracy, not to mention the training to interpret legal descriptions, establishment of control points, prorations, and a myriad of other issues.
For the viewers reading comments, this guy and his comment is dangerous to your bank account. As property owners YOU have the right to know where your approximate and sometimes exact property lines are located. My neighbor is building a swing set for his kids near the back property line and the Apps were perfect for him. But people like this want home owners to spend $1,200-$3,000 every time they have even a curiosity about the land they own. On my channel I just released a video about when to use a Site Plan, a GIS Map, or a Survey. Please look for it as it explains more. ruclips.net/video/OdM0Bhy7LFY/видео.html
I'm new at this so later on I might see something different in what he's saying pro or con. And maybe I won't. I wanted to know where my property lines are. I checked out the apps that do this kind of stuff. I ended up picking landglide. The explanations I found from what I wanted to know was watching his third and fourth video //I didn't see his first or second video,because I stumbled on a 3rd and 4th video// which makes sense enough where I didn't have to see the first and second video....which was easier for me to see and understand the the things I needed to do .I've watched I learned how to drop the PIN and get the coordinates to each corner and a lot more...., Someone will say I'm sure,, that's easy to do ..sure ,if you know it. I seen it I learned it and can do it now... I'm not saying I'm a professional but I get the concept.but when you first see it, it's not easy to understand,, cell phone wise... He also says which I like to,,,, is to hire a professional if need be he says this is just the tools to help you if you was wanting to do it yourself just so you can get an approximate idea where your lines are etc,,. . At this point I'm glad I chose landglide and I chose to watch his third and fourth video thank you Tommy. PS I didn't choose landglide because of their true free trial 7-Day period I chose it because what they say they could do, and it did what I wanted,. thank you also for the videos.
Hey Tommy. Great comment and thanks for watching those and understanding where I'm coming from. Many will watch 90-seconds of those 4 video's and then lash out with their anger. So, I appreciate your style.
A second of latitude is about 102 ft. A second of longitude at 45° latitude is about 78 ft. GPS canb do far better than these values. If a smartphone has dual frequency GPS capability it might have an accuracy of 2 meters. If it also has sbas capability, it might have an accuracy of 1 meter. You should look at the settings for Google Earth: I believe it will go to a resolution of 1 meter.
@@jimbell4137 Agreed Jim. I actually have a video where the 102' and my calculations were 80' across for the width. The SmartPhone is showing to be somewhat accurate, but my multi-channel Garmin is even more accurate.
Nice generalization of GIS and GPS, however, state laws for Land Surveyors dictate the degree of accuracy which is far greater than any of the hobby GPS can provide. Surveyors work and measure in one hundredth accuracy but the art of keeping that high accuracy, our state allows 1 in 5000 (1 foot of error in 5000 feet} in the most rural areas, in dense city areas the accuracy is astronomically higher. Lots of history and retracement, among other things the Surveyor does to protect his work so just hire a good surveyor, all the big numbers are misleading to the average person and accuracy is something that the Geographic Information Systems ignore.
Good points. Well received. The reason I assemble these video's is because consumers deserve to know where their approximate property lines are. My neighbor wanted to know where their back property line was because he was building a swingset for his kids. He did not want to spend $600 and wait 3 weeks for a Survey. For sure, Survey's are more accurate. But there are many reasons why approximations can work.
I got a metal detector on clearance to use at the beach. $32. I used it to relocate my metal pipe property lines after my whole neighbor pulled out the existing rebar. So, I relocated them and cemented the rebar just outside the metal pipe area. Spray painted the pipes orange first.
A fun treasure hunt but if you plan to do anything more than cut grass to these points, get a Surveyor. Otherwise, you're asking for trouble. Property disputes never end cheap or peaceful.
And yet 1,000's have used these methods to find their exact property corners. The most common method is to use the Apps to approximate the points. And then with a metal detector, find the exact OIP's in the field. Other Video's on my Channel show how to do this. @MarkTheRealtor
@@MarkTheRealtor Yep, all's well and good until one party disagrees or, as happens all the time, there is more than one iron at the corner, or no iron at all. Next thing you know, best friends are fighting and lawyers are billing hours. Nobody wins except the lawyers. There is a reason why surveyors and realtors are considered professionals; they know their business. A professional also knows when he's getting outside of his business.
@@rickhofsess84 There is a video on my channel for 15 USE Cases. For some, a Survey is for sure the best. And for others, a Survey is overkill and just not needed.

0:12 Mark, when were you a passenger on any space flight? Or when did you last traverse the equator? Without answering those questions in any affirmative manner, maybe you should stick with "We'll have to agree to disagree", on the earth shape issue. I'm taking other people's word that it's round also. 😜 BTW, fun and interesting content.
This guy is purporting facts which are not true. He assumes every property has accurate coordinates rectified to a specific geiod. His representation of accuracy is misleading. Hire a professional land surveyor to actually determine property lines.
For people reading these comments, the accuracy during my videos is Measured right on the Video.. Sure it's easy to say "Hire a Surveyor" but how many people are going to pay the $1,200-$2,500 for a survey. There are at least 20 reasons why homeowners want an approximation of their property lines with out paying all that money.
Hello Wizzardo. Good question. Each App will cast its own net. For LandGlide is has over 3,000 Counties in the USA and Canada. And I heard about some in New Zealand and Australia.
Hi Steven. Thanks for the note. You have me thinking. I have not been able to find Parcel Data on Google Maps. Have you? Now, on Google Earth with the Parlay 2.0 overlay, it has been useful. Coach me back please.
@@MarkTheRealtor Google earth shows parcels lot and you can walk around your property and somewhat find your pegs. but somehow their incorrect. Like my neighbors, the lot line is literally going over his house. It seems like that data is out of alignment. then they sell these maps with the incorrect data to other apps and services.
Hi Sharon. I just spent a month making a new video about this very topic. Please check back tomorrow as it gets released. There will be a link in the comments you can use.
my village was survey from opposite ends, east/west. this caused vast errors in property lines. some peoples' houses weren't on their property as an example. Two county employees came to my property boundary and told me that there was a road between my and my neighbor's property...but even the county didn't have the exact location. the road should be about 100' long. which is located about in our driveways. nothing ever came from it yet, but eventually something could happen due to the different original surveys of the town.
Ohhhh has nothing to do with the built in accuracy of gps and other tools you used. 🙄 you need to stop. BTW GIS stands for get it surveyed because most gis info isn't accurate unless it was surveyed 1st.
I can agree with you on one point. The accuracy comes from both GPS -and- the GIS County data. GIS does not stand for Get It Surveyed. Did you even watch the video? I did get it Surveyed and the results are shown and discussed. If you want to be 'snarky' please pay attention before you start typing.
@MarkTheRealtor I did watch it but do you know how many people are going to think they can survey their property using an app after watching? I also know that isn't what GIS stand for that's a surveying joke because so many GIS maps are not close to accurate. My friend uses onX and while we were hunting. He said this says it's your neighbors property can I park here. I said yeah that's my property, not his. It's closer in subdivisions like you sho, but rural areas are atrocious.
I live in st louis city. My house was built in 1921 long before it was incorporated into st louis city. The property survey from 1921 and from when I purchased my home in 1994 are the same. Talking with a new neighbour he kept saying the city owns the sidewalk and the grass/ tree strip to the road. I disagreed. But being curious I wanted to compare my property survey from 1994 when I purchased my home, with what the city has in record. I called the cities Recorder of Deeds Land Records Department. I first ask about who owns the grass/ tree strip. I was told the city does. I ask if I can come down and compare my survey with what they have on record and was told they don't have land surveys maps.. ? So how do they know what is what ? I know the city and utilities have easements for sidewalks, power, sewer, cable, planting trees along the street,etc.. But if they own it Id like to know when that happened, and why do I have to mow it and clean off the snow on it ?
The municipal authorities do own the planting strip and the sidewalk however it is the homeowner's responsibility to repair and upkeep these same areas. It was explained to me that this is a "citizen contract" we have with the government.
Relying on LandGlide, or any other GIS type service, for precise coordinates is foolish. Even Landglide tells you this: "The parcel lines within our database are fairly accurate. The property lines are not intended to represent actual recently surveyed property lines and are not recommended to use for legal purposes. Counties will rely on deeds and plats of record regarding disputes in the property lines." - The presenter may have said as much at some point, I was not able to watch deep into the video.
Nearly word for word from the disclaimers I make in the video's. Not exact, but often very close. And in most of my video's I hire a Survey team to check the Accuracy of the Apps.
@@MarkTheRealtor I expected that you would make that disclaimer, I had to run out of the office and could not finish watching it. - I happened upon it because of frustrations I have with surveys that I work with that never seem to agree with each other on their bearings, they also never agree with Google Earth, or my own compass bearings. When I am trying to find a pin that is 1500 yards away in a flat field just 1 degree of declination is troublesome, putting it mildly. I have a brand new survey that was just supplied to me, 60 acre parcel, and every single bearing on the survey is almost exactly 2 degrees off from what Google Earth claims as being True North. Thanks for the video by the way, from what I saw it looked very well done.
@@katy-fulshearrealestate7675 Great points Katy! Thanks for the positive energy. You sound like the type of person who knows this already....but here goes. Are you aware that True North and Magnetic North are different? The actual magnetic north wobbles every year and does not go through the North Pole. Weird right?
@@MarkTheRealtor Yeah, I am aware of this. I check and verify the latest declination on the day of my visits at the lat/long I am visiting. - The real question I have is for the survey crews that supply the surveys I work with. It's not the geo location points, but it's the bearings they show on the survey. - I have checked Google Earth (GE) bearings against a number of known geo-locations in the US - such as the Four Corners Monument, and GE is always within a 1/4 degree of the geo-locations marked bearings. So I have to assume that I can trust GE to be at least within 1/3 of a degree of accuracy, yet when I lay bearings on a brand new large-scale survey, the surveyor's shown bearings are off, and usually consistently within the survey I am looking at. Such as the one I mention above. In that survey, every single shown property line's bearing is off by almost exactly 2 degrees, 2 degrees higher than the bearings from GE. And it's not like the surveyor is showing Magnetic North, if so in this particular geo-location he would be under, not over. Are there any surveyors reading this that can answer that question? Do you check your equipment and make sure it's adjusted for true north? Or is this something that really doesn't concern you that much? In the end, if the readings are all consistent and the markers are all identified it really doesn't change much as far as the boundary lines are concerned. So maybe they aren't too worried about it? >>>> EDIT: So I got my question answered, at least mostly answered. I met the survey crew at the property this morning in order for me to see exactly where the marking pins were located. The bearings that are shown on the survey and the metes and bounds, they did not do. They don't take bearings themselves unless it's a new survey for a new parcel to be filed. In this case, they pulled all of the bearings off of the existing metes and bounds filed at the county and just wrote them into the new one. This property was originally surveyed about 60 years ago, so it's pretty difficult to know how good the equipment that was used was at the time.
Wow! This is as good as my ham radio hobby. Great detail, relatively easy to understand, use my Garmin 64s (dust off), and go outside. Thank you so much for explaining how to do this. Edit. Oops GE Pro no longer has Parlay 2.0 so I'll try the county method.... and rewatch your video.
@@MarkTheRealtor My garmin works fine. It's my State Plane map that list coordinates in Feet that I can't figure how to convert to Lat/lon. Easting & Northing conversion didn't work either.
This guy is missing the point. Property lines can't be determined digitally to the accuracy purported. He is blowing smoke with no professional credibility. Hire a professional surveyor. That's better than finding yourself in court because improvements are built across an inaccurate property line location.
I think the message is that GPS can provide an approximation, but can't be relied on for down to the foot, much less fraction of an inch accuracy. My concern is that even when professional surveyors are used, you may only obtain accuracy to within a foot, maybe inches, but even then, a margin of error exists. The point is that if your intent is to construct a property line barrier like a fence, wall, or hedge, some give and take with your neighbor may be in order, esp where uneven terrain or ground movement exists. IMO. G'luck.
Wow, how to use geo-technology related words and phrases almost 100% incorrectly! Your video title suggests, "any home", nope - this is USA-centric! You claim WiFi is involved in getting 6 decimal point accuracy, nope - those are simply calculated relative to the zoom-level. USA Military continuously "baby-sit" the GPS satellites - Tom Scott did a video on this - and accuracies are dependant on many factors, none of which you mentioned (certainly not the transformer box). Final resolution of even military GPS is never any better than about 1 metre. Your long/lat boxes at your location might well have those dimensions, however, try measuring same resolution boxes at higher or lower latitudes - the dimensions change. ...and I could go on, but I suspect my comment will be deleted!
Your Country does not have GoogleEarth and GPS (or other satellites)? I tested it the date With and Without WIFI and the accuracy was better with Wifi. My experience and your comment do not align. The accuracy was tested right there next to the Registered Survey. It seems you did not watch the entire video as it was right there in front of your eyes. Correct, Graticule boxes change based on the Lat/Long. No Duh! "Resolution Boxes" ? Really?
Using an app to find your property coordinates might work when you’re working with 100 acres but when you’re dealing with inches in a 50 x 100‘ city lot… That’s when you need a real surveyor‼️
Everyone needs a "real surveyor". Until they find out it's $1,200 and takes 3 weeks. Then people get to decide if they want to be approximate with Apps or exact with a Surveyor.

Amazing Stuff! I am his brother and also an engineer. I did not know any of this, and I will bet that the percentage of realtors who know this cannot be measured with the 6 digits after the decimal point! Imagine what he can tell you about your home construction and the process of buying a house!

Those 14", 32", 31" variances can get you sued and lose in court where you may have to pay your own legal fees, the court costs, and the other guys court costs. Get some quotes and get a real surveyor. I wouldn't depend on a geolocation mapping app. Satellites are off
For viewers reading comments, the solution you will see over and over again is to pay $1,300 or $2,500 for a Survey. Legally Survey's are supposed to be the most accurate, but I have had Survey's done where there was over 100' of inaccuracy. With the video's on my channel you have more tools to use now.
@@MarkTheRealtor tell them about dual-frequency GPS in smartphone, and sbas support.
very well done!!!!
Yes, thank you. This video needed effort.
super overview and exactly what I was looking for and appreciate the education on the accuracy and options available - just beginning to delve into the options out there and if I really need to hire a pro or can get close enough with what I am planning with my backyard.
Thanks for the not DO. Also on my Channel are 15 Use Cases that discuss when important Survey's are recommended and sometimes when they are not. My neighbor wanted to build a swing set near his back property line, and he felt like getting a $1,200 survey for that use case was not needed.
Guys. These apps work great for most everything. I’m a surveyor 32 years. Don’t hire me for things u can do urself with a mobile app. It really works
Thanks Jesse for the notes.
I suggest people buy those laser distance measure devices, $20-40 each. They measure 50-120 meters, and I've seen 150 meter and even 200 meter measure units. Sadly, I haven't seen an equivalently cheap angle measure device, a theodolite, or a way to make a total station. Sure, a professional surveyor would call this a 'toy', but technology advances by providing older technology at lower prices than before.
Thank you for sharing Jim.
Hi Mark. Very interesting video. Many thanks. I have now used Google Earth to plot a rectangular area in a field. I have the coordinates... however, what app are you using to enter the coordinates so that when you go into the field you can walk to the "exact" spot? In your video there appears to be a map with a clinometer overlay. What App is that (and how do you get that "view"?
Hi Mark. Okay, good work. The App I use to walk to Latitude and Longitude dots is Coordinates Plus by Mapnitude. It has been a huge help. Also, GoogleMaps can work if you enter the coordinates in the search bar where normally an address would go.
Subbing JUST for the flat Earth dig ❤
Thanks Folee. Was hoping that did not disappoint anyone. It certainly is new news.
This method helped me locate a property stake, buried in a densely wooded area. Got within 5' using a Garmin Foretrex 601. But when the trees leafed out it became impossible to return to the same location. The limited number of satellite signals was the cause.
Good work Rick. I like it.
What do the buzzers mean in your video? I thought you mispoke but I saw no correction
Thanks for the note. The buzzer is typically bad news.
All helpful but 23 inches is 23 inches. In fact, one inch is one inch. My very good neighbor is a little concerned about the property line and I want to be agreeable with him as much as I possibly can. I am certain where one property line is in the front. I used to be certain where the opposite front line is but can no longer find the marker that was there but I know the edge of the walk was placed on the marker. Both of us have a desire to be liberal with the rear property lines that are on a golf course. I think the rear marking were covered up by the third party. If one of the trees planted there falls over fifty years from now it could be a problem. But, it won't be my problem because I won't be here to see it. I think I'll check with the county and see what they have to say. I have a free app on my phone called GPS tools. It is helpful in so many ways but I need those coordinates to do the job. Right now I have 37 satellites I can count from inside my house. I can clearly see their coverage and quality. My altitude is 1001 feet and I am at xx degrees 5x'29.161'W. I think I need more accuracy on those last 3 numbers.
Thank you for the note. Sounds like you are on it. I like it.
minimg claims are located with a discovery post and corner posts that are all determined from the location of the first post, i.e. post #1 by township, range, section and sometimes divisions of the section, se nw etc. then post #2 is X number feet in the direction from the first post. post #3 and #4 follows suit. no gps coordinates are marked. lots of inaccuracies and no updates on the location method. However the BLM uses gps machines that are very accurate to record where the digging on the claim is to happen. They don't tell you those exact coordinates...maybe you have to ask for them? So a miner could be digging out of bounds and not know it.
So interesting. It does sound like a complicated puzzle.
Mark apology for the weird ask - but I've been trying to get hold of an inflatable globe like yours in that size for months! Any links? Much appreciated. Really learned a lot from your video, didn't realise what could be done with existing software.
Hi Dan. Sure, no problem. I found mine on Amazon and have used it so many times. Search "Huge Inflatable Globe, 1 Meter in Diameter, Earthball". The volume is so vast, consider going to a gas station and using there tire inflation pump.
@@MarkTheRealtor much appreciated!
I paused to see if I would have to sign in.. One of several Geometric aspects you did not mention and this one should be is the Satelite positiona relative to your Phone. Your Phone (Receiver) was held or mounted on a Pedistal. This adds around a yard above the spot you marked. Satelites are usually anywhere from 10 to 90 deg abobe the Horizon in any direction incurring a significant paralax error. This should be considered in your calculations. I guess for best relative accuracy your Phone would have to be on the Ground. thanx jw K5JDW
Hi John. It's a pedestal. And it was about 40" off the ground. During the readings there were 12 or more satellites tracking the location at all times. The parallax to which you are referring over that 40" of height may have caused the measurement to be off 0.00001 meters which is roughly the width of a human hair. I'm not putting the Garmin or my Phone on the ground for that type of tolerance.
This is ok getting ideas of the corner are.
There's a lot of misinformation. The gps in-accuracy is on the receiving end, antenna and app resolutions, not that we live on a globe.
Hi R. For most of my adult life GPS accuracy was a real issue. The GPS chips are so much better now. When I go outside with my Garmin devices they detect between 12-18 satellites at the same time and triangulate between all of them. THAT is one reason why they are much more accurate than in 2015. Technology wins.
Some may be the measurements for the chord of a very small arc, not a counting for elevation change or surface profile length.
Well received. Thank you for your thoughts.
Ok here is something to be careful of. Those pretty lines put on GIS maps aren’t the legal property lines. They are put in many times by summer help and interns
Frequently they missing offsets and angles
I’ve run into a number of situations where this has happened and do have other surveyors
So if you want to do it right you have to go off the actual coordinates those are what are actually recorded on plats
The lines are for people scanning property on maps to get a good feel of the boundaries
GPS isn’t accurate enough on your phone.
The difference between Survey accuracy and GPS phone accuracy is clearly shown on most of my video's. On video and on spreadsheets. When you say it isn't accurate enough. May I ask, for who?
Another excellent video
Thank you. This video was longer than I expected. I should have simplified it.
My neighbor has replaced the original metal markers with his own 8-10” nails by hammering them in the posts of my fence. The original metal pins were in the former fence, that he took out. How can I find the exact measurements without using metal pins?
Do surveyors always use metal markers, or is it possible to physically measure from the corner lot along the street to each house?
This does sound like a Licensed Surveyor needs to come in and figure it out. They have the equipment and expertise to be precise. Sorry this is happening to you.
thanks for the series. GPS has 15ft accuracy unless differential GPS is used.
Hi Joe. Over 100 experts have told me the 15' cushion and now measuring over 200 properties, I have not found that to be true. At least in my part of Missouri, when I slow down, let the devices acclimate with 15 satellites connected, they are almost always within 3' of actual survey stakes.
As magnetic north wanders around.
Many old surveys "set" the basic plan..

I understand exactly what you are saying however I don’t think we can locate our properties exactly by using GPS numbers. From what I understand, our government messes with the settings so they aren’t always exact. If they don’t want you to find an exact point, they can adjust the settings so they are not accurate, well at least that’s what I’ve always been told. Somebody please correct me if I’m wrong. Thank you.
Thanks for weighing in Frank. Yes, I too have heard that intentional bias is added. In measuring dozens of properties I own or have under contract the accuracy is rarely outside of 5' and usually within 3'. Many of my parcels have had a survey prior, but the pins have been covered over the years.
Until 2000 something called S/A, or selective availability was used to deaccurize GPS but that was ended. For a long while smartphones used GPS that was commonly reference to be 10 meters accurate, though it was probably more like 5 meters. Recently smartphones have been built that have something called dual frequency GPS and sbas corrections. If your phone has both, the accuracy approaches 1 meter. If you're willing to spend about $600, you can get a GPS receiver with an accuracy of about 10 millimeters, a technique called RTK. But you will have a lot of learning to do. Even then, the problem is that most survey drawings don't even reference latitude and longitude: they reference distances to stakes in the neighborhood.
Lol some lots have no meets and bounds. Mine was only a written description of land features that was written in a different language.

Thanks YTI for watching. Hopefully there were a few lessons learned in here.
Is there any way to get within a few inches?
With the current technology available to the public, I think this is the best we can do. Surveyor's have more expensive equipment and can get very accurate.
I have the coordinates. I will look into getting a Garmin. Thank you.
I was able to find some pre-owned ones on Amazon that were half priced. They are so accurate that they have become my favorite handheld.
When I used Google Earth and Parlay I get this image showing property lines running through my house and houses in my neighborhood. Any way to correct? I also checked municipal maps and see the same error.
Hi Main. Okay, that is brutal. It sounds like an issue with your County GIS Dept having that plat shifted over 50'?
That’s because GIS uses tax maps. Tax maps only show the property lines approximately. When you open up your local GIS it probably has a disclaimer explaining that GIS is not exact.
@@tybrady4598 the lines are so fast off they could not even be considered "approximate".
As a title company owner we find surveying mistakes all the time. They get testy when a title company calls them and informs them that the legal description they wrote is wrong. Title companies insure these properties and are liable for the accuracy of what we put in the title policies. The surveyor can be held liable also.
Great points. I order and pay for 60 Survey's a year and 10% of them are wrong. Often they are dead wrong. And the surveyors do enjoy saying the Title is dysfunctional. Sometimes, not always, they're right.
This guy is dangerous. Misleading information is worse than no information. What good is a DIY survey that is only accurate to 4 ft. A professional survey is good for 1:10,000, or 1/8th of an inch. Yea, it's expensive but so is the equipment to produce the accuracy, not to mention the training to interpret legal descriptions, establishment of control points, prorations, and a myriad of other issues.
For the viewers reading comments, this guy and his comment is dangerous to your bank account. As property owners YOU have the right to know where your approximate and sometimes exact property lines are located. My neighbor is building a swing set for his kids near the back property line and the Apps were perfect for him. But people like this want home owners to spend $1,200-$3,000 every time they have even a curiosity about the land they own. On my channel I just released a video about when to use a Site Plan, a GIS Map, or a Survey. Please look for it as it explains more.

I'm new at this so later on I might see something different in what he's saying pro or con. And maybe I won't. I wanted to know where my property lines are. I checked out the apps that do this kind of stuff. I ended up picking landglide. The explanations I found from what I wanted to know was watching his third and fourth video //I didn't see his first or second video,because I stumbled on a 3rd and 4th video// which makes sense enough where I didn't have to see the first and second video....which was easier for me to see and understand the the things I needed to do .I've watched I learned how to drop the PIN and get the coordinates to each corner and a lot more...., Someone will say I'm sure,, that's easy to do ..sure ,if you know it.
I seen it I learned it and can do it now... I'm not saying I'm a professional but I get the concept.but when you first see it, it's not easy to understand,, cell phone wise... He also says which I like to,,,, is to hire a professional if need be he says this is just the tools to help you if you was wanting to do it yourself just so you can get an approximate idea where your lines are etc,,. . At this point I'm glad I chose landglide and I chose to watch his third and fourth video thank you Tommy. PS I didn't choose landglide because of their true free trial 7-Day period I chose it because what they say they could do, and it did what I wanted,. thank you also for the videos.

10:38 - Flat Earthers trigger warning.
Too funny. Thanks for the laugh.
google earth, the website, is only giving 1 second of accuracy. How are you getting the fractions of a second?
On top of the Google Earth standard accuracy, I overlay Parcel 2.0. It was easy to install.
A second of latitude is about 102 ft. A second of longitude at 45° latitude is about 78 ft. GPS canb do far better than these values. If a smartphone has dual frequency GPS capability it might have an accuracy of 2 meters. If it also has sbas capability, it might have an accuracy of 1 meter.
You should look at the settings for Google Earth: I believe it will go to a resolution of 1 meter.
@@jimbell4137 Agreed Jim. I actually have a video where the 102' and my calculations were 80' across for the width. The SmartPhone is showing to be somewhat accurate, but my multi-channel Garmin is even more accurate.
Nice generalization of GIS and GPS, however, state laws for Land Surveyors dictate the degree of accuracy which is far greater than any of the hobby GPS can provide. Surveyors work and measure in one hundredth accuracy but the art of keeping that high accuracy, our state allows 1 in 5000 (1 foot of error in 5000 feet} in the most rural areas, in dense city areas the accuracy is astronomically higher. Lots of history and retracement, among other things the Surveyor does to protect his work so just hire a good surveyor, all the big numbers are misleading to the average person and accuracy is something that the Geographic Information Systems ignore.
Good points. Well received. The reason I assemble these video's is because consumers deserve to know where their approximate property lines are. My neighbor wanted to know where their back property line was because he was building a swingset for his kids. He did not want to spend $600 and wait 3 weeks for a Survey. For sure, Survey's are more accurate. But there are many reasons why approximations can work.
I got a metal detector on clearance to use at the beach. $32. I used it to relocate my metal pipe property lines after my whole neighbor pulled out the existing rebar. So, I relocated them and cemented the rebar just outside the metal pipe area. Spray painted the pipes orange first.

A fun treasure hunt but if you plan to do anything more than cut grass to these points, get a Surveyor. Otherwise, you're asking for trouble. Property disputes never end cheap or peaceful.
And yet 1,000's have used these methods to find their exact property corners. The most common method is to use the Apps to approximate the points. And then with a metal detector, find the exact OIP's in the field. Other Video's on my Channel show how to do this. @MarkTheRealtor

There is a reason why surveyors and realtors are considered professionals; they know their business. A professional also knows when he's getting outside of his business.
@@rickhofsess84 There is a video on my channel for 15 USE Cases. For some, a Survey is for sure the best. And for others, a Survey is overkill and just not needed.

This guy is purporting facts which are not true. He assumes every property has accurate coordinates rectified to a specific geiod. His representation of accuracy is misleading. Hire a professional land surveyor to actually determine property lines.
For people reading these comments, the accuracy during my videos is Measured right on the Video.. Sure it's easy to say "Hire a Surveyor" but how many people are going to pay the $1,200-$2,500 for a survey. There are at least 20 reasons why homeowners want an approximation of their property lines with out paying all that money.
Does this work for any property around the world or is this for US properties only. Just wondering as there is more to the world than the US.

Two county employees came to my property boundary and told me that there was a road between my and my neighbor's property...but even the county didn't have the exact location. the road should be about 100' long. which is located about in our driveways. nothing ever came from it yet, but eventually something could happen due to the different original surveys of the town.
Very interesting Richard. Thanks for sharing.
i guess you dont know the basic properties of water eh? :P
Ohhhh has nothing to do with the built in accuracy of gps and other tools you used. 🙄 you need to stop. BTW GIS stands for get it surveyed because most gis info isn't accurate unless it was surveyed 1st.
I can agree with you on one point. The accuracy comes from both GPS -and- the GIS County data. GIS does not stand for Get It Surveyed. Did you even watch the video? I did get it Surveyed and the results are shown and discussed. If you want to be 'snarky' please pay attention before you start typing.
@MarkTheRealtor I did watch it but do you know how many people are going to think they can survey their property using an app after watching? I also know that isn't what GIS stand for that's a surveying joke because so many GIS maps are not close to accurate. My friend uses onX and while we were hunting. He said this says it's your neighbors property can I park here. I said yeah that's my property, not his. It's closer in subdivisions like you sho, but rural areas are atrocious.
I live in st louis city. My house was built in 1921 long before it was incorporated into st louis city. The property survey from 1921 and from when I purchased my home in 1994 are the same.
Talking with a new neighbour he kept saying the city owns the sidewalk and the grass/ tree strip to the road. I disagreed. But being curious I wanted to compare my property survey from 1994 when I purchased my home, with what the city has in record. I called the cities Recorder of Deeds Land Records Department. I first ask about who owns the grass/ tree strip. I was told the city does. I ask if I can come down and compare my survey with what they have on record and was told they don't have land surveys maps.. ?
So how do they know what is what ?
I know the city and utilities have easements for sidewalks, power, sewer, cable, planting trees along the street,etc.. But if they own it Id like to know when that happened, and why do I have to mow it and clean off the snow on it ?
Thanks for sharing. I'm sorry I do not know how to solve this one.
The municipal authorities do own the planting strip and the sidewalk however it is the homeowner's responsibility to repair and upkeep these same areas. It was explained to me that this is a "citizen contract" we have with the government.
@@TheDroppedAnchor Thank you for sharing this knowledge. Well received.
Relying on LandGlide, or any other GIS type service, for precise coordinates is foolish. Even Landglide tells you this: "The parcel lines within our database are fairly accurate. The property lines are not intended to represent actual recently surveyed property lines and are not recommended to use for legal purposes. Counties will rely on deeds and plats of record regarding disputes in the property lines." - The presenter may have said as much at some point, I was not able to watch deep into the video.
Nearly word for word from the disclaimers I make in the video's. Not exact, but often very close. And in most of my video's I hire a Survey team to check the Accuracy of the Apps.
@@MarkTheRealtor I expected that you would make that disclaimer, I had to run out of the office and could not finish watching it. - I happened upon it because of frustrations I have with surveys that I work with that never seem to agree with each other on their bearings, they also never agree with Google Earth, or my own compass bearings. When I am trying to find a pin that is 1500 yards away in a flat field just 1 degree of declination is troublesome, putting it mildly. I have a brand new survey that was just supplied to me, 60 acre parcel, and every single bearing on the survey is almost exactly 2 degrees off from what Google Earth claims as being True North. Thanks for the video by the way, from what I saw it looked very well done.
@@katy-fulshearrealestate7675 Great points Katy! Thanks for the positive energy. You sound like the type of person who knows this already....but here goes. Are you aware that True North and Magnetic North are different? The actual magnetic north wobbles every year and does not go through the North Pole. Weird right?
@@MarkTheRealtor Yeah, I am aware of this. I check and verify the latest declination on the day of my visits at the lat/long I am visiting. - The real question I have is for the survey crews that supply the surveys I work with. It's not the geo location points, but it's the bearings they show on the survey. - I have checked Google Earth (GE) bearings against a number of known geo-locations in the US - such as the Four Corners Monument, and GE is always within a 1/4 degree of the geo-locations marked bearings. So I have to assume that I can trust GE to be at least within 1/3 of a degree of accuracy, yet when I lay bearings on a brand new large-scale survey, the surveyor's shown bearings are off, and usually consistently within the survey I am looking at. Such as the one I mention above. In that survey, every single shown property line's bearing is off by almost exactly 2 degrees, 2 degrees higher than the bearings from GE. And it's not like the surveyor is showing Magnetic North, if so in this particular geo-location he would be under, not over. Are there any surveyors reading this that can answer that question? Do you check your equipment and make sure it's adjusted for true north? Or is this something that really doesn't concern you that much? In the end, if the readings are all consistent and the markers are all identified it really doesn't change much as far as the boundary lines are concerned. So maybe they aren't too worried about it? >>>> EDIT: So I got my question answered, at least mostly answered. I met the survey crew at the property this morning in order for me to see exactly where the marking pins were located. The bearings that are shown on the survey and the metes and bounds, they did not do. They don't take bearings themselves unless it's a new survey for a new parcel to be filed. In this case, they pulled all of the bearings off of the existing metes and bounds filed at the county and just wrote them into the new one. This property was originally surveyed about 60 years ago, so it's pretty difficult to know how good the equipment that was used was at the time.
never assume your GPS is accurate. The newest retail models are better but not like commercial grade products.

@@williamokrasinski9840 Good question William. I'm not sure on that one. There are some Garmin tutorials on RUclips that perhaps could help?
This guy is missing the point. Property lines can't be determined digitally to the accuracy purported. He is blowing smoke with no professional credibility. Hire a professional surveyor. That's better than finding yourself in court because improvements are built across an inaccurate property line location.
I think the message is that GPS can provide an approximation, but can't be relied on for down to the foot, much less fraction of an inch accuracy.
My concern is that even when professional surveyors are used, you may only obtain accuracy to within a foot, maybe inches, but even then, a margin of error exists.
The point is that if your intent is to construct a property line barrier like a fence, wall, or hedge, some give and take with your neighbor may be in order, esp where uneven terrain or ground movement exists. IMO. G'luck.

Surveyors can get things down to about about half an inch or even tighter if need be.
He specifically says this is why you need a professional surveyor at 12:15. Maybe listen to the video before ripping the guy a new one.
Definitely need a surveyor, the error is only less than half inch.
Wow, how to use geo-technology related words and phrases almost 100% incorrectly!
Your video title suggests, "any home", nope - this is USA-centric!
You claim WiFi is involved in getting 6 decimal point accuracy, nope - those are simply calculated relative to the zoom-level.
USA Military continuously "baby-sit" the GPS satellites - Tom Scott did a video on this - and accuracies are dependant on many factors, none of which you mentioned (certainly not the transformer box). Final resolution of even military GPS is never any better than about 1 metre.
Your long/lat boxes at your location might well have those dimensions, however, try measuring same resolution boxes at higher or lower latitudes - the dimensions change.
...and I could go on, but I suspect my comment will be deleted!
Your Country does not have GoogleEarth and GPS (or other satellites)?
I tested it the date With and Without WIFI and the accuracy was better with Wifi. My experience and your comment do not align.
The accuracy was tested right there next to the Registered Survey. It seems you did not watch the entire video as it was right there in front of your eyes.
Correct, Graticule boxes change based on the Lat/Long. No Duh!
"Resolution Boxes" ? Really?
@@MarkTheRealtor Maybe instead of WIFI you meant WAAS?
THE EARTH IS FLAT- THE SCRIPTURES
Thanks David for the laugh.
Using an app to find your property coordinates might work when you’re working with 100 acres but when you’re dealing with inches in a 50 x 100‘ city lot… That’s when you need a real surveyor‼️
Everyone needs a "real surveyor". Until they find out it's $1,200 and takes 3 weeks. Then people get to decide if they want to be approximate with Apps or exact with a Surveyor.
@@MarkTheRealtor why would you need “approximate” property lines? You need exact lines so you know where to put the fence and order to build
@@corevette My neighbor was building a playfort for his kids and wanted to know where his back property line was so he stayed on his land. It was perfect for that application. On my Channel there is a video of 15 use cases. For some, Survey's are the best way to go. But not always please.
No where accurate enough. If it helps you find a surveyor’s pin that’s great but just using the apps and gps without finding a corner pin is worthless. Hire a surveyor if you really need to know where your property lines are.
@@polyuniverse1908 So my neighbors wanted to know where his back property line was so he could build a playfort. The Apps helped him find the back property line within a few feet. It helped, and he didnt' spend $1,200 and wait 3 weeks for a Survey. That's just one example of 15 that I have.
He is wrong.
I am so sorry this video disappointed you. I will try to do better next time.
No, just no. Timothy L. Blackmon, PSM
And yet 1,000's have watched this video over and over because it has helped them. With over 2,000,000 views this channel is helping property owners say Yes, just yes.
Surveying has been made so much easyer🦧 now that the Earth is Flat 👩🏫
Yes, good point. And all the grid lines are big rectangles.
