Amazing video, thank you!

Will this tool work with .laz files too?

Tidal forces (variable according to time of year, month, and day) continiously influence and change the shape of the geoid to a greater magnitude than earthquakes and volcanic activities.

Title should be corrected, this discusses Class B not Class A. Also, click the "Miami TAC" to see the Terminal Area Chart for MIA. It greatly declutters the airspace. Cheers!

As for Mining, is there a way to get >400 ft of depth penetration in narrow spaces?

Thanks, Dr. J - this has been the most clear, concise, and best explanation of this technology I've been able to find on the RUclips. I'll keep watching your stuff, appreciate the thoughtful presentation and the deep understanding you are communicating.

Hang on, at 17:45, shouldn't it be Class E airspace starting at 700 ft AGL because of the magenta shading?? You said it's 1,200 AGL because there's no other indication... but thers that shaded magenta (which I understand overrides the default start of Class E at 1,200 AGL down to 700 AGL) Admittedly, for the UAS pilot, 1,200 and 700 only makes a difference if we're looking at a structure higher than 300 ft, but we might be. Can you clarify?

Great explanation for engineers with different backgrounds

Great channel you curated here, will you do a video on the GPS survey of GCPs and how it works in practice? (you speak about it in the end of the video...) I have a drone mini 3 and GCPs plates from amazon but I dont know how to get the GCPs coordinates, a lot of people saying I have to have a base and then a RTK module? is it right? Thanks mate and keep the great channel!

how long would you say it takes to run? I am working with a .las file from the New York State lidar collection and it seems to be taking a very long time.

I see that the concept of parabola is used to explain the typical reflection signature in GPR data, but it surprises me a lot as it is a hyperbola.

Thanks for your explanation.. I was wondering about how we get variogram model ? Best

I struggled with stable and unstable air. The easiest way for me to remember it (if it makes sense for anyone else) is this: stable air is cool weather. the air is stable with fog because fog is commonly associated with cool air, continuous participation because that keeps thr air cool while showery participation gives the air the ability to warm up, smooth air (obvious why), and then poor visibility because poor visibility is again commonly associated with cool air. Unstable air is all things that gives the air the ability to warm up, thus making a UAS work harder. Not sure if any of this made sense to you guys but that's the way I remember stable vs. unstable air.

Is a bare earth DEM a DSM?

Thanks great stuff…

Hi Jeremy, i tried to use your code example with my DataFrame, but in the Ordinary Kriging, my curve didnt ajust. what can be the problem?

Hi! I'm joining a high-school level quizbee on geodesy and geomatics organized by the geodetic engineering program of our university. Can you please give some pointers on what to focus on studying as the competition is for highschoolers. Also, some suggestions on what to expect on question types and such. Thank you so much sir❤

Hi

Thanks alot Best tutorial for insar data i have seen so far. May i please have your email address In case i need professional help.

You didn't quite explain the purpose of PPP and how the new lat/long information is used. Should it not be entered into Emlid Studio at all?

Thank you for the interesting lecture!This might sound like a very basic question. But how does one calculate displacement in mm/year? I noticed that absolute displacement between the reference image and secondary image is obtained initially. And as time go by, and more and more images are obtained, the absolute displacement will still be relative to the reference image. Would that mean that the rate of displacement should be (displacement)/(time since reference image)? This way of calculating rate would result in a decreasing rate of displacement as time go by, given time will always be increasing. Another method is to find the change in displacement between 2 images, and extrapolate it to a year. E.g. [(displacement between 1jan and 1feb)/(31)]*365 -> however, this tends to make displacement values extremely large. Too large and it is alarming. Wondering are there any industrial norms to calculate rate of displacement in mm/year? Thank you!

how did you get the xyz of those GCPs? thank you! great video!

Thanks for this video! Weather was my last hurdle to clear, and this helped me immensely during test prep.

ok, this is the best explanation of autocorrelation, covariance, semivariance, and variograms I have ever seen. will definitely be sending this to people who are new to geostatistics and spatial/temporal interpolation.

thanks, this is very helpful

Sir, how semi variogram is computed?

Once you have generated the random array you can copy and paste values so it doesn't recalculate every time you change a worksheet cell.

You are the first one that made the perfect explenation ... I have now my docker and wsl running on the cpu`s and mem and swap i want. Thank you.

thanks, super helpful!

Thank you so much. That was so useful.

is this processing for observations made in Canada or anywhere else

Thank you !

Thank you for providing this lecture. It helps me to understand GNSS products.

thanks for the video!!!

😍🥰

Thanks man

The fact that the FAA is intentionally ambiguous about terminology and exact circumstances pertaining to the issue of flyingnover people shows they either 1) don't want anyone flying over people 2) are intentionally gate keeping 3) Are attempting to make money or influence the industry through compliance waivers 4) Are an inefficient bureaucratic entity - these conclusions aren't mutually exclusive though. They haven't approved any drones for cat 2 or 4 and have only 1 for cat 3 which is fixed wing and costs a gazillion dollars

Excellent introduction, would you mind if I use for a Computer Science class? We teach algorithms for solving equations in class.

So if I don't have a known point, could I use static observations and ppk to get a known point. Then, setup the base station on that known point I created, then configure the base and rover to rtk, and then use the rover to place gcps, and then use emlid studio to correct the gcps and then use that data to create accurate maps and models?

Really cool presentation :)

great video, wish you did the substitution of lambda back into the formula

Jeremy, Thanks for the help. Your channel was the only thing I could find with regards to risk management and detailed weather explanations. Took my 107 today and got an 88. Thanks again!

Hello doctor, I urgently need your help on a very important matter. Can you help me and teach me? No one is helping me, please..

amazing video, good luck, im physicist too, student

Good summary. Wish you would’ve left the cold front diagram up a little bit longer.

Very helpful and explained well thank you

Anyone needing to do coordinate system conversions you can do so here geodesy.noaa.gov/NCAT/ if you have a file with many entries you can choose the Multipoint option and upload a comma separate file. Tab sep prob works too.

Is it possible to use projected coordinates at all?

Olá tudo bem? Sou iniciante, voçe sugere alguma literatura?
