- This shows you a way you can set some check points that will allow you to do proper topos and verify and ensure you are capturing and building properly when doing your own layout and design work.
Thank you for your content, seriously a big help man.
your content is gold to me
How do you know what projection data to select?
Hello, thanks for info on your channel. So these "check" points? Are they actual northing, easting and elevation or are they made up coordinates? Just learning about this stuff and am a little ignorant.
👍🏼
Hello, thank you for your channel and uploading these videos they’ve been a big help for grasping the basics. By any chance do you know how to add surface design (final elevations) points to a partially completed surface design? I have the elevation points on paper and have been just been using the rover as a sort of laser but it would be a huge help to enter the points in the system
Sounds like you are wanting to create a design surface for the purpose checking grade. If you have the northing and easting coordinate associated with the point you can input the points and create a surface from them. It's really going to come down to what data you have and how your site is setup.
I know that probably isn't much help, but I'm not fully understanding what you're needing to accomplish.
I'm new to the topcon technology. What process did you go through when you set up your base station at the truck??
I'm setting it up as an unknown control point in the base station setup. This is just an autonomous position that you can use to localize a site or reference other points. There is another video that shows starting your base on an unknown point that may help.
So, if I understand this right between. The conversation between you and Deadpool is that when you switch back to GPS localize after setting points using the state plane that all you have to do is select "use horizonal & vertical" and you shouldn't have to remeasure? Maybe I didn't read that right.
For small jobs I just set my Base to 5,000 North 5,000 East and 100 Elevation and Measure the base pole.
I was told you can run a job on just one point. Is there any disadvantages to this other than its just not a tight site?
Nice work on the videos.
Correct, Deadpool is right in pointing out you can just select "use horz and vert" and you shouldn't have to re-shoot the points.
You can absolutely do a one point calibration, but I wouldn't recommend it on any job that is designed or engineered. The biggest disadvantage I have seen is in the possibility of some rotation, especially the further the job spans.
I tend not to do one-point calibrations because I like to have more than one point to check, so you can set some check points to verify with.
Appreciate it, I try, I'd like to dedicate more time to it, maybe one day I can get there.
The elevations it measures, is it in reference to some official datum point such as the australian height datum?
Unless you set it to use a different datum it will reference the ellipsoidal height.
Here is a link to a decent article explaining the difference between them.

I went to your website, k already have an IDig 2 d for my excavator, I have seen videos about 3 d with GPS in Europe. Do you know if or when it will be available in the USA ?
I'm not sure. I would imagine they would have it at ConExpo for debut. I can try and find out a release date, but as of now I have not heard one.
What's the set up for your data collector a
I'm using the ram Ball but come loose all the time
I'm guessing you have the Seco Ram Ball (5200-160). These tend to strip out and rotate after a while. I have gone to using a RAM tough claw (RAP-B-400U). They are a little more bulky, but seem to be more stable, cheaper and last longer.
Did you really had to measure all points all over again after setting the project to gps>localization? I mean you already had wgs coordinates, if you just check use horizontal and vertical you would get green color control point with 0 horizontal and vertical error since these wgs coordinates are exactly those local coordinates, I mean you are doing extra work for no reason and if the site is big you would lose a lot of time for nothing
I will have to try it. I'd assume you are probably right now that I think about it. Like I say several times in the video this is the way I do it and there are many ways to do things. Most places I use this is small sites. So I appreciate the comment because I learned something new, which is the reason I do this videos. I'm at least trying to add some value instead of dropping snarky comments on people's post.
@@ctpusa1 I made the same mistake with Trimble Access measuring points twice and then just realized the next day that both wgs and local coordinates are already stored in controller. Because of the nature of Trimble Access program I just had to export local coordinates and import them again as new points in the same job, because program only allows to combine imported with measured coordinates, and so I got localization with 0 horizontal and vertical error. The same would work with Topcon but even simpler just by checking those h. and v. boxes. Haven't tried it but i believe it would work and it would save you some time.
Btw. I am fan of you channel and I am so glad someone is posting this stuff, I already learned a lot from you channel so i think we are even now. Keep the good work!
