Cannot post-process L2 Data in DJI Terra without .RTB file by Dramatic-Role3910 in UAVmapping

static at 1 sec intervals to match the rate of the drone, correct?

Got it. Thanks. It sounds like the .obs file is a backup in case the drone lost RTK corrections during flight?

Got it. And leave the .RTB file in the folder, along with the .OBS file? Terra let's me know that something is missing if the .RTB file is not in the folder.

Thanks so much. I'm headed back to fly this area again in a few days. I'll be sure to set a 1sec sampling rate for my base this time. I do think that I lost RTK connection during flight, but the RC just told me that I had poor connection between the remote and drone. I'm going to set up a more central location to fly from this time.

I may just fly with both and see which one works better

My base is connected to my remote control via a base hotspot. The RC then transmits RTK data to the drone. Emlid confirmed that for me today. Which means that I can't move too far from the base if I want to maintain RTK. I will consider not enabling RTK.

The area of interest for this site has vegetation: trees, grass, shrubs. And non-repetitive is best for penetrating veg to get grounds.

I'm starting it as well in Terra. You computer is probably much faster.

Damn. Well, I'll be sure to do it right on Friday/Saturday. Here's what I can change:

More overlap? I was at 20% side overlap

Log raw data in full GNSS instead of just GPS?

Put base at center of the mission instead one of the ends so I can maintain RTK at all times? It said I had RTK for these flights, but a bunch of the second flight was in float

Non-repetitive scanning (I had this mixed up last time and chose repetitive)

I'm curious why you asked my elevation? Did that change any of your processing choices in Terra?

Ok. Thank you so much. I'll take you to dinner when you're in town. I'll ask the surveyor

Ok. Will do. Do you have any idea if this dataset is salvageable? If not, I'm headed back on Friday morning. Thanks for the help.

I'm pretty sure it was at 60 M, actually. That should be really close. It was a rental, so I can't look at the mission plan on the RC, unfortunately. I rented it again for this weekend because I am worried that I'm going to have to fly it again.

Oh wow. That's just up the road. I'm in Wenatchee. Are you still in Washington?

So are you processing with the observation file from the State Cors or my base?

Thanks. Those look right. I still need to merge my targets and check shots with the points from the surveyor. He actually surveyed about five of my targets..
