So I did a drone flight with my Mavic Air 2 and it made a really beautiful 3D model of the old rail yard I was photographing but I noticed a problem.
It reversed the high point and the low point of the ground somehow. The highpoint (with an elevation of 147 feet) shows up as -23.02 ft on the map (as in 23 feet below where the drone took off) and the lowpoint on the map shows up as 34.7 ft (real elevation of 140 ft). Other then the high/low point being flipped low/high its also showing a nearly 58ft difference from one extreme to the other when the real difference is only about 7 feet.
I tried using a calibration point to fix it but all that did was screw up the height map.
I am going to try flying the route again in the next few days using a Phantom 4 Pro to see if it still spits out broken data like that.
But hey, the 3D model looks very nice.
NVM… the 3D model is janked when exported.
