电子地图显示速度直接影响地图用户的交互感受,一直是地图制图者关注的一个重点。本文从地图显示速度与适人化交互操作的关系出发,分析了GDI与OpenGL的特点和差异,提出了基于OpenGL的电子地图显示的方法,重点对基于OpenGL多线程的电子地图快速漫游显示技术和基于纹理映射的地图要素符号化方法进行了分析讨论,并进行了实验论证。

The display speed of the electronic map affects directly the feeling of map users,and it is always the hot issues for the cartographers.This paper forms the relationship between the display speed of electronic map and the humanoid interaction,analyzes the characteristics and the difference between GDI and OpenGL,and proposes a new method based on OpenGL to display the electronic map.It discusses the speedy display based on OpenGL multi-thread and the map element symbolization method based on texture-mapping and verifies the results by the experiment.
