This paper proposes an SVG-based spatial analysis method to support spatial query and analysis in the Web environment. We discuss two issues of this method. First, based on the theory of spatial data modeling, we propose an SVG-based spatial information representation model to represent the needed geospatial data in SVG. Furthermore, this paper designs and implements some spatial operators and integrates them into an SVG-based spatial extended SQL to support spatial analysis on spatial data represented in SVG. This method can improve the functions of current WebGIS applications, most of which have been only employed for visualization. Finally, this paper implements the method and designs a case study to evaluate the proposed method.
