基于.NET的GIS地图符号库的设计与实现

地图符号是数字制图的基础,尤其在地理信息的系统中,表达地图内容离不开地图符号,本文对地图符号的概念、特点作了简要概述,在符号制作的原则和原理的基础上,采用面向对象的方法,在.NET平台下,结合ArcGIS Engine技术设计了GIS地图符号库系统。本系统设计分别包括了点状符号库、线状符号库和面状符号库,用户可根据自己的需要设计符号,可通过多种方式浏览各种符号,该系统具有通用性和开放性。

Design and Implementation of GIS Map Symbol Library Based on . NET

Map symbols are the base of digital map. Especially in GIS,map meanings are essentially expressed by map symbols. In this paper a brief overviewof the concept and characteristics of map symbol,this paper designs a solution for GIS map symbol library with the ArcGIS Engine technology based on . NET. The solution is combined with production principle and principle of map symbols,object-oriented method. This paper made the point symbol,line library,planar library symbol library. User can make their favorite symbol and can browse through their visual preferences symbols. The system has generality and openness.
