Load CityGML

Function Description

SuperMap iDesktopX supports directly loading CityGML data in the scene for browsing and viewing. CityGML (City Geography Markup Language) is an open data model and exchange format based on XML, used for storing and exchanging virtual 3D city models. It is an application schema of Geography Markup Language (GML) 3.1.1, published by the Open Geospatial Consortium (OGC) and the Geographic Information Standards Committee (TC211) of the International Organization for Standardization (ISO).

This function only loads CityGML data in the scene for visual browsing, and does not save the data to the scene.
