With the fast development of WebGIS， data fast transmission and browsing the electronic map by way of vector in WebGIS become the focus of present WebGIS research。 This paper proposes a method of establishing a Web-based system that can visualize geographic data。 In terms of the graphics format， our proposed system uses Scalable Vector Graphics (SVG) that XML-based 2D vector graphics， and geographic data stored on Web Server with XML database。 SVG is a language for describing two-dimensional graphics based on XML， and it can be used to describe the point， line and polygon。 The schema has a small amount of data transferred， faster performance， low development costs and so on。
