Technology of 2D vector map display based on OpenGL

LIU Jia-jia;LUAN Xiao-yan;BIAN Shu-li;Institute of Surveying and Mapping,Information Engineering University;Troops 96669;Troops 61540;  
The display speed of electronic map affects directly the feeling of map users,and it is always the hot issue to the cartographers. This paper through forming the relationship between the display speed of electronic map and the humanoid interaction,analyzed the characteristics and the difference between GDI and OpenGL,and proposed a method based on OpenGL to display vector map.It discussed the speedy display based on OpenGL multi-thread,the map elements symbolized method based on texture-mapping and verified the feasibility by experiment.
