Level Up Your Drone Data with Only ONE GCP 

This is the best video I've seen explaining the whole process.

Fantastic lesson and workflow demonstration. Thanks!

Great job Jason! Very well thought out

Nice job. I especially like the cartoon. Lol. Good stuff

I just wanted to say thank you! Very useful/helpful video!! 45 mins flew by. I’ll have to rewatch a few times to actually catch on to all the different points you made. Thanks!

Amazing video Jason, thank you! James from DroneDeploy here. I think the real reason that the RTK and PPK do not line up is that they are based on different datums. If I had to guess, the PPK matched the AeroPoint as they both using CORS networks that are using the nad83(2011) datum, whereas I guess the RTK2GO corrections were using the more global WGS84 and most recent ellipsoid. Both maps were processed with very high accuracy, and are likely absolutely referenced in XY to within 0.2ft vs their reference datum. Anyway, your workflow to resolve that was great, thanks for sharing. If you want them to match perfectly in the future inside the DroneDeploy interface then you'd need to use an RTK network that uses a NAD83 datum. I think most CORS in the US will be using NAD83(2011).

Excellent job with your explanation of the process. Do you do courses

Great video Jason (like the name)! I was wondering if you could do a video or share some insight to using a Reach RS2+ on site with the M3E? How accurate would that RTK data be? How do you verify the accuracy without a known checkpoint? I am just getting started and have no survey knowledge, only RU-vid U…but I’ve learned a lot. I noticed you used ArcGIS to verify your checkpoints, but am clueless as to what to do. I’ve tried my local Cors station and RTK correction (via Emlid studio) but don’t know how to verify that either. Please shed some light please. Much appreciated! BTW…I just got the Reach RS2+.

Great video, thanks Jason. I've watched it a couple of times but could you please confirm that in this case the aeropoint has only been used as a checkpoint and not as a GCP in DD processing? Thanks!

That was a really good explanation. Maybe i'm picky (or confused); but you were explaining about PPK, and @29:56 you got into RTK post processing tab on topodrone. Does that make a difference over the workflow?

Thanks for the video. I guess I am having trouble understanding the practical implementation of this. In the video you are intentionally selecting a site based on the proximity to a CORS station and survey markers. Is this possible in more remote sites? What if you are outside the suggested 15km radius and have no survey markers?

I'm curious if you would mind doing a similar video but capture GCP markers with a GNSS+RTK receiver.

Couldn't watch the whole thing with that background music so repetitive - otherwise I think this would have been a great video.

Very helpful, thank you, could you please remove or keep it lower music on the background
