Abstract
With the development of LBS(Location Based Services), transportation of spatial data in wireless Web has become hot point in current research. After the existing solutions are compared and extended in the paper, a new SVG_ based solution is provided to represent and compress spatial data. And then the key technologies in the fields of SVG data compression are researched and resolved, in which the improved compression method combined simplified SVG representation and GZIP compression. The test result showed that SVG based method is appropriate to represent geodata in LBS, and the improved way to compress SVG based data is better than traditional way, in which the feasibility of the solution is validated.
