Hi Amir,
Thank you for responding. Indeed it has been a while.
I am excited to finally be able to get elevation data on our points. We have good LIDAR coverage, and area covered is growing. We also are continually adding survey control with x, y, and z geometry.
I hadn't considered using 3d analyst to solve the problem. I can do comparison testing pretty quickly.
Again, thanks for responding.
Best,
Bob
