How it works
- DSM + DTM raster pair: two
.tiffiles covering the same area on the same grid. The server subtracts the DTM from the DSM, clamps negatives to zero, applies the union of both inputs' NoData masks, and wraps the result as a COG. - LAS / LAZ point cloud: a single classified point cloud. The server finds ground points (ASPRS class 2), computes each point's height above its 3 nearest ground neighbours, then takes the per-cell maximum at 1 m pitch.
- Either path ends with a COG hosted at
helios-lidar.org/output/<id>.tifplus a copy-paste YAML snippet for the Helios card'slidar-local-ndsm-*config keys.
