摘要
以传统地图中要素表达要求为依据,分析了GIS中要素表达所存在的问题与产生的原因及其表现形式,提出了通过图层顺序控制、程序算法、符号分层绘制等多种方法来解决问题,提高了GIS可视化质量。
Firstly the problems of formal representation in GIS are researched and analyzed according to the representation demand of traditional cartography. Then, according to the reasons and representation style, the problems are divided into two classes. According to two types of problems, many solutions, such as programming algorithm, symbol layered drawing and others, are used to solve the problems, in order to keep GIS visualization fit for the demand of cartography and improve the quality of GIS visualization.
