摘要
阻碍网络GIS性能的因素分为两大方面:硬件环境和软件环境。聚焦于软件环境,从通用网络GIS的三层体系架构上入手,分别在数据层、逻辑层和层间数据传输上描述了的一些可实施的优化途径及其技术原理,以综合应用来提高网络GIS的效率。
Obstacles to efficiency of WebGIS are classified as hardware environment and software environment. The article focused on the software environment and based on the three layers of GIS construction, point out some available optimizing approaches applied on the data layer, logical layer and transport layer and described respectively technical principles of these approaches. These approaches can be used assembly to improve the efficiency of WebGIS applications.
