CityGML Integration Into the ArcGIS Platform
For 3D applications and environmental simulations, including urban planning, mapping the energy characteristics of buildings, or noise mapping, a variety of (open) standards are available in CAD, BIM, and GIS domains for the storage, visualization, and transfer of 3D geospatial datasets. Examples of open standards are OGC’s CityGML and Indexed 3D Scene Layers (i3s). These formats are essential to many organizations dealing with 3D datasets. Whereas CityGML is meant to be a data model and exchange format, i3s is designed to stream large amounts of heterogeneous data.
