- Abstract: Urban basic surveying and mapping results are an important data source for constructing spatial geographic information database. Combined with the warehousing work of Zengcheng aerial map data, this paper elaborates the process of DLG data warehousing based on CAD structure to realize the transformation from topographic map data to spatial geographic information data. 城市基础测绘成果是构建空间地理信息数据库的重要数据来源。结合增城市航摄成图数据入库工作详细阐述了基于 CAD 结构的 DLG 数据入库过程实现由地形图库数据到空间地理信息数据的转换。
