General / Re: Why is cloud and DEM so distorted from simple dune-like texture?

Hi
You'd better compare the original image with the orthomosaic, instead of the vertical view of the point cloud. The lack of patterns on the sand can contribute to a more noisy DEM. Always look at a shaded relief image of the DEM to assess its quality. You get better results with the sun at a smaller altitude angle.
