Hi..I'm a student, nedd help for my thesis project =)
Does anyone know how to filter the LiDAR data? I had created the raster file from LiDAR ascii format. I need to produce an EDM. The problem is, I do not know how to filter the non ground data from the raster, so that there are only ground data left. Any help is much appreciated =)
