The dataset contains a digital 3D City model of the Floriade district in Almere, the Netherlands. The digital model is encoded in CityGML standard, and includes different CityGML thematic modules: Building, Vegetation, Land_Use and Relief (topography). The model is derived from a masterplan provided by the Urban Design Department, City of Almere in October 2018. The original data included AutoCad plans, a SketchUp model of the buildings, a tree database and a raster image of the topography. The harmonization of the original data was carried out in Safe Software's FME.
