REST架构的WebGIS技术研究与实现

Research and implementation of WebGIS based on REST architecture

随着Web Geographical Information System(WebGIS)技术的快速发展,人们已不满足目前其基于简单网页技术的表现效果和交互性,而需要寻找更好的技术和方法来解决矢量地图的发布、服务器端和浏览器端更快的响应速度、更加理想的交互性等瓶颈性问题,同时对系统伸缩性和开发简洁性也提出了更高的要求。为此,本文以WebGIS为研究对象,针对当前WebGIS空间数据的共享和互操作存在的问题,深入分析基于REST技术架构的GIS WEB服务技术模型,探讨如何将REST技术应用到WebGIS开发和应用中,在提高WebGIS的表现力与交互性的同时降低开发的复杂性,提高系统的可伸缩性,并有效地解决了数据的共享性和可交互性等问题。

With the rapid development of the Web Geographical Information System（WebGIS）technology,the users have not been satisfied with the performance and interactive effects of the current WebGIS based on simple web-page.The researchers want to find the best method to solve the difficult problem of how to support the release of vector map,how to fast response of the server side and client side,and how to support the interaction.In addition,the scalability of system and simplicity of development are also higher demands.Therefore,this paper aimed at solving the spatial data sharing and interoperability problems based on WebGIS,and deeply analyzed GIS Web Service technology model based on REST.This paper also studied how to improve the performance and interactivity of WebGIS while reducing development complexity,and increase system scalability,and also effectively solve the problems of data sharing and interoperability.
