That sounds good. I would like to know if he has to be prexact on his altitudes and what kind of software he uses for the stitching.

He uses a 4 MP camera and makes multiple passes. He stitches the video together with software. Each pixel in the resulting image is 1 centimeter. The construction company uses this as sort of an asbuilt. They file this and can look later to see where rebar is in the cement floor and walls. Where plumbing goes through cement, etc. He does this at multiple stages of the construction process. You could definitely do what you are asking about according to what he is doing.

Sometimes we fail but most of the time when we hit something there is no paint or flags. I am wondering if a drone video would be better than our handheld phone/camcorder footage? I have never used a drone personally but have seen some of the images. It sure would be quick and easy to fly a route. Not sure the altitude you would want to use. Not sure if it would see more than the camcorder on the ground. I am thinking that the aerial view would see the paint better but the ground view would see the flags. Be good for engineering I would think. Hopefully much better resolution than Google earth. I wonder if you can correct the perspective distortion? -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
