- The page cites a 35-million-ground-point DTM taking about eight minutes on a workstation, with times varying by computer and cloud size.
Field notes
The page lays out a five-step sequence from point-cloud classification through drawing production, with custom classes trained from labeled tiles and precision and recall reported per class. It lists outputs in formats including GeoTIFF, LandXML, IFC, SHP, DXF, and DWG. The published timing examples are identified as workstation measurements, and the page cautions that actual times vary with hardware and point-cloud size.
