Study of WebGIS based on XML Database and SVG

摘要

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.
