I would like to suggest that the data processing include an option to filter out vegetation and structures, such as buildings, to produce a terrain model of the ground only. I have found the option to export a contour dxf, but there is no option to export the actual terrain model as faces (triangles).
Unless you are doing conceptual work auto-DTM’ing from cloud processing is a pipedream. If people want very accurate DTM’s they should think about post-processing the point cloud. I’ve used 5 different softwares and none of them can even consistently and accurately recognize stockpiles.
