CityGML: An Open Standard for 3D City Models

turlif 投稿 "CityGML is an open data model and XML-based format for storing and exchanging virtual 3D city models, implemented as an application schema of GML3, the extensible international standard for spatial data exchange developed within the Open Geospatial Consortium (OGC) and ISO-TC211. It is a common information model for representing 3D urban objects. CityGML defines classes and relations for the most relevant topographic objects in cities and regional models with respect to their geometric, topological, semantic and appearance properties. It is currently in "beta"."
