摘要
近年来,网络技术的迅速发展,推动着GIS在更大范围内的应用与普及,Web GIS作为网络GIS的一种,极大地促进GIS的应用与普及。然而由于缺乏有效的支持矢量数据的标准方法、没有成熟的地理数据缓存技术等种种因素限制Web GIS的发展。基于新一代的Web的标准HTML5新特性Canvas和web Storage、AJAX技术,提出一种新型的Web GIS实现方案,能够有效地改善现有Web GIS所存在的缺陷,提高Web GIS的分析处理能力。
In recent years, the rapid development of network technology, promotes the GIS in a large range of application and popularizeation, WebGIS as a GIS of network, greatly promotes the application of GIS. However, due to the lack of standard method of support vector data effectively, and lack of mature geographic data cache technology and other factors limit development of webGIS. Based on the new generation of Web standard HTML5 Canvas and webStorage, AJAX technology, presents the realization scheme of a new kind of WebGIS, can effectively improve the existing defects of WebGIS, improve the ability of analysis and processing of WebGIS.
