I am getting terrible DSM results on asphalt surfaces, with point jumps of over 8m (25’) at times. I have tried all 3 surface smoothing options, increasing the number of matches, using geometrically verified matching, and high resolution 3D textured meshes. Every process version results in a ragged surface that causes wild jumps in the orthomosaic. This only happens on the asphalt surfaces and not in the sagebrush/natural terrain.
Here are some examples:
The DSM and Orthos are clipped in the same area. As you can see in the overview, the pattern of point cloud degradation is limited to the tarmac.
Has anyone else seen this pattern or are there any other settings to try?
Thanks for any help!
