Quick piece of advice please? So i have 3 separate drone data capture jobs. All are similar in that I’m flying about 240 - 300m above ground, taking images that overlap by 80% or so etc.
All process sweetly in ODM, ortho looks great, 3D looks great.
When creating contours, two of the jobs return data that looks about right (ie im expecting elevations of 350, to 400m above sea level and thats what I am getting). The third job is returning strange numbers that range in value from -9 to +8m. The site is reasonably flat and a 20m variance would be about right, but above sea level should read about 90m.
Ive processed them exactly the same. Ive also looked at the EXIF and they all contain the same info, as I would expect as I have used the same drone (P4 Pro II).
