数字地形图自动化缩编技术的探讨——以南海区1∶500到1∶2000、1∶5000地形图的缩编为例

Discussion on Automatic Compilation Technology of Digital Topographic Map:Taking Compilation from Scale of 1∶ 500 to 1∶ 2 000 and 1∶ 5 000in Nanhai District for an Example

文章结合南海区数字地理空间框架的建设方案,探讨利用现有1∶500数字化地形图,采用自动综合与缩编技术编绘1∶2 000、1∶5 000地形图的方法,目的是建立一套符合《佛山市国土资源地理数据规范》要求的多尺度地形图数据库,以满足国土资源管理和城市规划建设的需要。

By taking the construction of digital geo-spatial framework in Nanhai District as an example, this thesis discusses how to use the automatic synthesis and compilation technology to compile 1：2 000 and 1：5 000 topographic map based on 1 ： 500 digital topographic map. Its aim is to establish a multi-scale topographic map database which can meet the needs for Geographic Data Specification of Land and Resources in Foshan City, so as to meet the requirements of land and resources management and urban planning.
