[QUOTE="Vilco, post: 71710, member: 4957"] The problem in in the precision: if you look at the 2 GPS lat/lon fields you'll see the last 3 decimals are all the same, and if you take many vertical pictures (ortophotos) at 5 meters of distance each one while moving the Spark forward, you'll see that they all have the same exact GPS lat/lon coordinates for 4 or 5 phots, then the coords will change and remain the same for the next 4 or 5 pictures. With just 3 decimal digits, It takes circa 20 to 30 meters to see the coordinates change, and this messes up any attempt at geo mapping. Anyone has found a workaround for this? I know I can edit the exif data with the correct ones if I find them, but i didn't find them in any of the log/dat/txt files I found in the GO 4 app folder on the phone nor in the drone itself (linked to PC via DJI Assistant 2) nor via airmap editing these dat files, and I don't want to go through the GO 4 app, find the spot of the single photo, read its correct coords and go update the exif of the single picture and repeat all of this 200 TIMES or more :) So I made an appplication in C#, it asks for a folder, the one containing all of the pictures, and a file, a log file conteining the correct exif data and the images' names.
