That helps a lot. Whew, maybe I wont go blind.
Good morning all. We made it through Monday. We flew a little job on Saturday. They said the targets were down and gave us the go. The client is a land surveyor. They put targets on the ground which are usually a 4ft x 4ft white X on the ground and they shoot in the GPS coordinates with their survey grade GPS accurate to 1/8th of in inch. Depending on the size of the project we want from 5 to 50 targets. We then run the project through our software and then go find the target in the image and punch in the X, Y and Z position of that spot of ground.
When we re-run the project it ties the project to a very tight tolerance to the earth. Without the targets we get to maybe 2 feet of reality. That is fine for just a photo, but it you want to tie past surveys and current data back to the image it needs to me a lot closer.
Anyway they are always in a hurry to get the data back ASAP. We have been waiting on them to get us the ground control values so we can finish it and writhe the invoice. More hurry up and wait.
