C IL | Well, you can get LiDAR that accurate from a plane (helicopter). Costs a lot.
Canucker or someone on here was possibly doing some topo mapping from a drone. Never did learn the accuracy of it.
I don't think you would want to design something requiring 1-2" contours from LiDAR, based on my current knowledge. I am hoping something great and awesome comes up soon though in the drone world to make this cheap and affordable. | |
