Morning gents!
Photogrammetry huh, I had that course when I was still in school, but not the stereo version.
Lol, I found it hard enough in 2D.
It is indeed a proven technique, moreso than laser suveys. I actually don't know if laser surveying is more reliable now, I've been out of the survey loop too long.
It's a bit odd that you still need assistance from a surveyor on the ground, but I suppose it is the best way to do it.
Are you very weather dependent? I suppose you do not need cloudless skies and have tot do the surveys preferably around noon to minimize shadows, or do you?
Oh yes, guys, IT IS FRIDAY!!!!!!!!!
And that's just fine by me!
