摘要
在参考现有地物分类标准和CityGML要素类型基础上,探讨遥感专题模型的设计方法,分析基于CityGML的几何拓扑、语义属性信息表达机制,并以一小区域数据验证了方法的可行性。
Based on the references of existing standard of ground object classification and CityGML feature classes, the paper studied design method of RS thematic model, analysed representation mechanism of geometric-topology and semantic attribute information based on CityGML, the methold was validated through data of a small region.
