摘要
地图符号是数字制图的基础,尤其在地理信息系统中,地图内容的表达离不开地图符号,本文对比分析了目前一些地图符号库的设计方法和实现技术,结合地图学、地图符号化的基本理论,采用面向对象的方法、关系数据库理论和XML技术,在NET平台下设计了GIS地图符号库系统。该系统具有通用性和开放性,可以实现多个平台的地图符号数据共享。
Map symbols are the base of digital map. Especially in GIS, map meanings are essentially expressed by map symbols. Comparing and analyzing the design method and implementing technique of cartographic symbol base, this paper designs a solution for GIS map symbol library based on .NET. The solution is combined with map symbol theories, object -oriented method, RDBS, XML technique. It provides an excellent approach to share map symbols in many platforms.
