“数字城市”建设中的地图综合技术

在“数字城市”建设中,完成了基本比例尺地图数据建库后,面临的紧要问题就是如何维护更新数据,以及建立跨比例尺数据间的联系,数字技术环境下的自动化地图综合技术成为必须解决的技术问题。通过“数字深圳”空间数据基础设施建设实际,讨论了数字环境下地图综合的概念、实施路线及软件开发方法,对多尺度空间数据库建设有关问题进行了思考。

Cartographic Generalization Technique for Digital City Construction

After building the basic map database, the construction of digital city faces the urgent questions on how to update the data and how to link the database across multi-scale. The cartographic generalization technology under digital environment becomes a key technology to maintain the map database. Based on the experience of spatial infrastructure establishment in digital Shenzhen construction, this paper tries to discuss the issues of digital map generalization including the new concept under digital environment, realization strategy , software development method and the construction of multi-scale spatial database.
