I've been following this guy that is planning to regreen a dry part of Texas and in this episode he has 2 guys with a bunch of DJI equipment that will help him out map his terrain.
Pretty cool to see.

Very cool.    If your interested in making your own 3d models check out the luma app,  it can take poi videos from the drone a make photo models that you can move around in.

Thanks. It is not my interest per se, but it is interesting to see for sure.
