传统三维城市建模局限于可视化和信息共享困难,OGC为此推出CityGML。本文以房产领域为例,研究基于CityGML的应用领域三维建模方法,探讨CityGML框架下的应用领域专题模型设计方法,分析三维空间对象的信息描述及可视化机制,并以一小区域数据验证了本文方法的可行性。
Due to the limit of visualization and information sharing difficulty in traditional 3D urban modeling,OGC launched CityGML.This paper took housing domain for example,to study the 3D modeling methods in application domain based on CityGML frame by: discussing thematic model designing way in application domain in CityGML frame;analyzing information description and visualization mechanism of 3D spatial object.The method of this paper was validated through test data of a small region.
