WebGL中在线动态地图服务框架的设计

Design on the Online Dynamic Map Service Framework in WebGL

随着无线通信技术的飞速发展,现代电子地图逐渐向信息传输、地图显示、动态地图等方面发展。因此,传统的二维地图已经不能满足社会的需要,需要不断完善在线动态地图。基于浏览器技术的WebGL技术已经成为一种新的工具,可以帮助Web实现新的地图引擎功能。基于GIS技术,可以设计出实时、高效、可扩展、安全可靠的地图引擎。通过WebGL技术,可以绘制大量的矢量数据,这也可以提高服务器的加载速度。该文首先分析了在线动态地图的功能,进而提出了相关算法,最后构建了一个在线动态地图服务框架。

With the rapid development of wireless communication technology,modern electronic map has gradually changed to many aspects,such as information transmission,map display,dynamic map and so on.Therefore,the traditional two-dimensional map can not meet the needs of society,which needs to constantly improve the online dynamic map.WebGL technology based on browser technology has become a new tool,which can help the Web implement new map engine functions.Based on GIS technology,a real-time,efficient,scalable,safe and reliable map engine can be designed.Through WebGL technology,a large number of vector data can be drawn,which can also improve the loading speed of the server.This paper first analyzes the functions of online dynamic map,then puts forward relevant algorithms,and finally constructs an online dynamic map service framework.
