摘要
通过对目前GIS中电子地图显示的分析研究,指出了GIS中空间信息地图显示存在的问题。针对目前电子地图显示模式的单一性、显示环境的多变性和显示效果的平淡性,提出了电子地图显示模式的概念。指出了影响地图显示模式变换的因素主要有空间数据的用途、屏幕比例尺、使用环境和显示的设备等,并分析了常用地图显示模式的可视化特点。对基于多种地图显示模式的符号库和显示模板进行了初步的研究,为深入研究空间信息可视化进行了初步尝试。
In the base of research on the map＇s vision in space information of GIS, the paper indicates the problems of the map＇ s vision in space information of GIS. Now the display pattern of electronic map＇ s oneness, the display environment of electronic map＇ s levity and the display effect of electronic map＇ s wateriness, the paper puts forward the conception of the display pattern of electronic map. This paper goes deep into the main factor of display pattern of map, such as use of space information, screen scale, use environment and display equipment. And it analyzes some map＇s display patterns which are used usually. Then the paper makes some research on the base of multi-display pattern of map＇ s symbolic database and display template. Also some basic practices of space information＇s visualization are made.
