tum nyc 3dIn this student project a semantic 3D city model of New York City (NYC) has been created based on datasets provided in the NYC Open Data Portal. Different 3D feature types were derived from existing public 2D and 2.5D datasets using spatial and semantic transformations together with (some) photogrammetric analyses. The resulting 3D city model is represented in a homogenized and integrated way using the international standard CityGML of the Open Geospatial Consortium (OGC). It comprises all NYC buildings, land parcels, roads, parks, the digital terrain model, and water bodies – all with 3D geometries. To the best of our knowledge it is the first publicly available big 3D city model of a large city in the USA which is based on official governmental data. We provide the resulting CityGML / KML / COLLADA / glTF datasets for download as Open Data as well as 3D web-based visualizations of the entire city model on this project web page. Read More
