Abstract
Aiming at the problems of sharing and interacting of WebGIS spatial data,the extension and interaction characteristics of the SVG technology based on XML were analyzed.And taking the XML based SVG as vector image,a new WebGIS model was proposed to effectively solve the problems of spatial data sharing and interacting.And then the SVG based WebGIS model was analyzed.
