Design and Implementation of an Open Location Service System Based on SVG

As a language for describing two-dimensional graphics in XML,SVG(scalable vector graphics) can be implied to display spatial data.In this paper,the possibility of SVG used to trans-fer spatial data from server to client is discussed.Based on SVG technology,an open location service system conformed to J2ME and J2EE specification is designed and implemented.Pocket PC,as an example of mobile information terminal,displays the result of spatial analysis and process in LBS.
