Dutch governmental department for maintaining boundaries for ownership (Kadaster) choose CityJSON as format for 3d modelling gis. I suggested to a FME specialist to look at a way to convert it to ifc for use in “bim software”. Now the FME service is able to convert CityJSON to either 3d dxf (semi open) as well as gml. I have no clue for what reasosn CityJSON is the preferred “bim standard”.
Anyone have background about and about possible conversions, its limitations and possibilities? For use in pratice! Not theory
