Field notes
GeoAlt combines cadastral context with RGE ALTI, LiDAR HD, urban-planning layers, and parcel-level calculations in a browser workflow. The homepage lists four professional views, including cut-and-fill volumes and littoral constraints, and names outputs such as classified point clouds, surface meshes, DXF 3D, IFC, E57, and XYZ files. It distinguishes preliminary LiDAR work from the regulatory survey performed by a surveyor.
