GeoBIM benchmark CityGML data - Rotterdam Lod12 and BuildingsLoD3

These are the three CityGML datasets provided for the ISPRS EuroSDR GeoBIM benchmark initiative. They represent: - some districts in Rotterdam, in LoD1 and 2; - random buildings in LoD3, generated with the open source random3Dcity software. Their full description can be found at https://3d.bk.tudelft.nl/projects/geobim-benchmark/rotterdamlod12.html https://3d.bk.tudelft.nl/projects/geobim-benchmark/buildingslod3.html respectively. The initiative was funded by ISPRS Scientific initiative program and co-funded by the European association for Spatial Data Research (EuroSDR)
