一种地类图斑符号配置算法

地图符号配置是地图可视化的重要组成部分,传统的土地利用现状图制图中,地类图斑的符号化通过填充法或填绘法实现,但是这些方法不能解决符号的空间冲突问题。本文从地图认识的角度出发,归纳地类图斑的符号化规则,提出了一种地类符号配置算法,并利用C#语言、Arc Engine开发接口实现了该算法。实验结果表明,算法较好解决了地类符号与其他地物要素压盖问题。

An algorithm for symbol configuration of land type

Map symbol is the language of the map.It is the basic means to express geographical things,and plays an important role in cartography.Map symbol configuration is an important part of map visualization.In the mapping of traditional present land-use map,the symbol of land polygon usually is filled through the filling or plotting methods,but these methods cannot solve the problem of symbol’s spatial conflict.According to the map knowledge,summarizing the rule of symbolizing the land polygon,this paper advanced a method to deploy land-symbol.This method was created by C# and Arc Engine.Experimental results indicated that the algorithm could solve the spatial conflict between land use symbols and other map features.
