Give the model a point layer (a station, school, GP surgery or proposed site) and it downloads the OpenStreetMap streets, footpaths and buildings around it with QuickOSM, removes ways people cannot walk on, and finds everything reachable within 5, 10 and 15 minutes along the network at 4.8 km/h (about 800 m in 10 minutes, as in Manual for Streets). Reachable paths are buffered into catchments, cut into bands and cumulative catchments, and every OSM building is counted in each. Walking speed, band times and catchment width are all settings.
Eight Bozmaps QGIS models in one zip: flood, landslide, wildfire, NDVI, NDVI change detection, land surface temperature, OSM map generator and vegetation vulnerability.
Screens how far inland a tsunami of a height you choose could reach, from a DEM, a coastline and land use roughness, using the published Berryman height-loss method.
Zone of Theoretical Visibility for a proposed wind turbine, mast or tall building, with visible area by distance band and the buildings that can see it.
