基于ArcEngine的供水管网GIS符号库的设计与实现

在供水管网地理信息系统建设过程中,地图浏览和制图输出是最基本的建设功能,地图符号在这些功能中起着非常重要的作用,人们对地图可视化表达和使用的要求越来越高。根据我国GIS技术规范和供水行业标准的要求,重点阐述了ArcEngine环境下供水管网地理信息系统地图符号库设计与制作的实现方法。在符号的制作过程中采用了抗锯齿的技术,减弱了ArcGIS平台下图形锯齿化的问题。

Design and Implementation of Water Supply Network GIS Symbols Library Based on the ArcEngine

In water supply network geographic information system construction process,maps and drawing output is the most basic construction function,map symbol in these functions plays a very important role,map visualization representation and the demand of use are higher and higher.According to our country GIS technology norms and water industry standard requirements,it emphatically expounded ArcEngine environment water supply network geographic information system map symbol library of design and manufacture methods of realization.In the production process of symbols we used anti-aliasing technology and reduced the jagged graphics ArcGIS platform of the problem.
