宁夏1∶50000地形要素数据的缩编更新

Implementation of Map Generalization Updating for Ningxia 1∶50000 Terrain Database Features

介绍了利用省级1∶10000数据成果进行1∶50000地形要素数据缩编更新的技术路线方案、实施过程,同时探讨了生产过程中一些技术问题及处理方法,对今后1∶50000地形要素数据缩编更新生产具有一定的借鉴作用。

This paper described the technologies solution and the implementation process using 1 ： 10 000 data resuits to update the 1 ： 50 000 terrain feature database, and discussed some technical problems and solution in the production process, which has a reference to the 1 ： 50 000 terrain feature database generalization updating production.
