Abstract

SVG(Scalable Vector Graphic) is scalable vector graphics that is a rule of description of vector graphics. Because a lot of features of SVG are very consistent with characteristics of WebGIS, now there are many GIS websites based on SVG. As the SVG document itself does not preserve the topological relations, it’s difficult for spatial analysis. This paper introduces a method of overlay analysis based on SVG. The purpose of this paper is to provide an algorithm of overlay analysis based on sample data structure.
