About this model

Build a ready-to-style base map without leaving QGIS. The model queries OpenStreetMap for buildings and roads inside your area of interest, reprojects them to your DTM's CRS, fills small gaps and clips your surface and terrain models, and adds three fields to every building: mean DSM (Z_mean), mean DTM (T_mean) and their difference, an estimate of mean height above ground (height_m). It also produces a slope layer. Ideal as the first step of flood, wildfire or urban studies.
