Ingredients

A raster Digital Elevation Model (DEM) is necessary. For the purposes of osm_LoD1_3DCityModel a DEM is a bare-earth raster grid; the surface of the earth free of natural and man-made features.

Hereafter; depending of the processing strategy the needs are slightly different.

Village/CampusDistrict [This is on hold]
With the Village/Campus strategy nothing
more than the raster DEM is necessary. osm_LoD1_3DModel will call overpass-turbo for the osm contributions		 osm_LoD1_3DModel will access osm contributions through Pyrosm

Due to the substantial amounts of data in the osm.pbf extract; Districts requires a bit more.

osm_LoD1_3DModel uses osmconvert to make the osm.pbf more manageable.
It does this through selecting only the data from a specific area.

osm.poly files, that cover various regions around the world, are available for this very purpose.

osmconvert and a osm.poly file for a region of choice
