摘　　要：当前,3D建模技术在城市测绘等方面具有广泛应用,但是3D地理空间数据量较为庞大,因此,建设城市的3D地理空间存在一定的困难。对此,论文介绍了地理空间模型构建关键问题,阐述了数据源与实景3D模型数据构建方法,并对数据模型进行了分析。At present,3D modeling technology is widely used in urban surveying and mapping,but the amount of 3 D geospatial data is huge,so there are some difficulties in the construction of urban 3D geospatial.In this regard,this paper introduces the key issues of geospatial model construction,expounds the data source and real 3 D model data construction method,and analyzes the data model.
