I´m trying to model building rooftops based on a LiDAR dataset. I've already interpolated using Delaunay's triangulation a DEM with 1 meter resolution. Due to LiDAR data is not accurate in building edges, I managed to get cadastre data so I have building boundaries.
Does anyone know how to build a 3D model of rooftops based on the previously mentioned inputs (DEM and cadastre data).
Any help would be highly appreciated.
