摘要
矢量地形图数据是基础地理信息数据库建设的基础,本文分析了数字城市空间基础数据建设中碰到的一些问题。初步探讨了外业南方Cass6.1地形数据与大比例尺基础地理信息要素数据字典之间的异同,给出了解决方法,并应用于实际项目,取得了良好效果。
Vector topographic data is the foundation of the basic geographic information database construction. This paper analyzes the digital city in the construction of urban space infrastructure some of the problems encountered. Points out that the similarities and differences between the South Cass6.1 data with large scale geomatic data. Finally, gives the solution, and applies to some projects, and makes a successful.
