GIS环境下的地图综合

Map Generalization in GIS

讨论了地图自动综合的基本概念、数据模型和常用函数；试将两类不同性质的地理信息分开存储，提出了主从式地理数据库模型，试图解决新数据模型中引入的数据一致性问题；最后给出了一个用规则库来实现的地图综合方法。

This paper introduces the generalization concepts data model and basic functions in common interactive generalizationtools, and intends to extend the traditional georelational data model to incorporate the generalization information in new data modelnamed master-slave. Meanwhile, this paper tries to solve the consistency problem in the new data model, and puts forward animplementation of map generalization with rules database.
