Research And Implementation Of WebGIS Application Based On AJAX Technologies And REST Style Architecture

WebGIS(Web-Based Geographic Information System,) is a new technology based on Internet,developed after GIS,which is the best solution to implement the interoperate.WebGIS was born from the combine of the Web technique and GIS technique.The user of WebGIS can browse the spatial data of the WebGIS site, make map of special topic,search and analyze any from spatial data at one of the Internet site.The researcher want to find the best method to solve the difficult problem of how to support the release of vactor map,how to fast response the server side and client side, how to support the interaction.The real time WebGIS not only faces the above hard work,but also solves the problem of how to get the real time data and reflect the change and refresh the map at the clint side.The researcher must resolve the entire problem.Aiming at the problems of sharing and interacting of WebGIS spatial data.Based on the analysis of the new framework WebGIS design model of Ajax technology and REST architecture style.The new WebGIS model was proposed to effectively solve the problems of spatial data sharing and interacting.This paper researched on the Ajax rich client development and REST style architecture,and through the leading provider of WebGIS sohu.com Inc.,whose product application Sogou Map of the design and development proved to Ajax technology and REST style architecture of ascension the website performance and user experience.
