摘要
本文从应用的角度,对地图符号库的组织和访问机制进行了研究,并首次引入显示控制样式的概念,同时对显示控制样式在地图符号化中的应用进行了深入研究。实践证明,该研究成果可以很好地解决多地图符号库管理和高效访问问题,控制地图的显示效果和改善地图的显示速度,另外还可以兼顾地图屏幕显示和打印输出效果。
The paper researched on map symbolization from application vision. First, the paper researched on organizing and accessing mechanism of map symbol database. Then, the authors proposed a term-display control style, and went deeply into researching on it' s application in map symbolization. Through practical application, went the achievements can be used to primely serve the manage- ment and efficiently accessing to multiple map symbol database, control map display effect, improve map display speed, and obtain same display effect both on screen and printer.
