The　contradiction　between　Distributed-　GIS　massive　data　and　the　limited　bandwidth　of　network　resources　is　becoming　more　and　more　serious,　inquiry　of　distant　vector　data　and　transmission　of　massive　data　become　the　crisis　key　of　the　problem.　Based　on　analyzing　the　method　of　massive　data　inquiry,　combing　with　the　query　optimized　method　of　spatial　database　and　the　cost　function,　we　proposed　a　novel　vector　data　inquiry　method　which　is　optimized　and　can　transplant　to　the　client.　The　experiment　proved　that　this　method　is　effective　on　improving　the　inquiry　speed　and　maintaining　a　good　network-load　performance.　©　2008　IEEE.
