Abstract
The network geographical information system faces some difficulties that the Web language does not support vector graphics.Thus delivering a great deal of variety spatial data is limited by the network bandwidth currently etc.Aimed at solving these problems in the geography information system,this paper analyse SVG technique and its advantages,puts forward system structure and work principle of WebGIS based on SVG technique.In this way,application of SVG technique has the good development foreground in WebGIS.
