In　order　to　better　render　and　access　geographical　data　in　Web　browsers　and　resolve　the　bottleneck　problem　caused　by　a　large　number　of　simultaneous　spatial　analyses　in　WebGIS,　this　paper　first　makes　mapping　between　the　space　objects　and　the　SVG(scalable　vector　graphics)　labels　using　the　real　time　interaction　of　SVG,　so　that　the　space　data　can　be　easily　released　in　the　Web　browsers　and　the　users　are　able　to　conveniently　access　and　manipulate　geographical　data.　Then　a　novel　WebGIS　model　is　proposed,　which　utilizes　the　computing　ability　of　the　Web　browsers.　This　model　is　different　from　the　traditional　distributed　computing　systems　as　it　can　promote　cooperative　work　between　the　server　and　the　Web　browsers　and　can　quickly　accomplish　huge　computing　tasks　in　parallel.　Finally,　a　prototype　system　is　realized　to　verify　the　feasibility　and　the　advantage　of　the　model.
