Highlights: We present a novel algorithm for generating pit-free Digital Surface Models directly from raw point clouds. It can generate both raster and TIN outputs. It considers all points (not only first returns) and avoids pit creation by "freezing" higher-up triangles as it constructs a pit-free TIN using incremental constrained Delaunay.
