Yes. My bad. Hit send b4 editingLooks like some fat fingering without him paying attention. I think he means,
If I was to do a waypoint mission using litchi over a roof, would it measure the rood dimensions as well as pitch? If not, what is a good app for doing this?
I think I translated correctly. I can't really answer his question though. I use Litchi but I have never use it for that purpose. I think the answer is going to be no because you really can't do anything but capture images so you would need to have some point of reference or scale that you could measure off of. Now if you are just doing an estimate of roof size for pricing out a roofing job, I am sure you could guess from the images with a reference, but if you want to be exact, Litchi wouldn't do it for him I don't think unless there is something in there I am missing. It definitely won't give him pitch in any way.
