First,　this　paper　uses　tile　pyramid　model　based　on　SVG　to　realize　raster-vector　integration　on　mobile　GIS　platform,　then　a　new　storage　architecture　with　two-level　cache　buffer　is　designed　which　can　speed　up　the　system　to　retrieve　the　data　of　map　tiles.　J2EE　and　J2ME　technologies　are　used　to　make　the　mobile　GIS　platform　with　high　scalability　and　modularization.　Finally,　this　paper　verifies　the　feasibility　and　efficient　of　the　platform　through　a　test.　©　2011　IEEE.
