Abstract：

This　paper　is　an　introduction　to　the　design　and　implementation　of　a　communication　mechanism　for　WEBGIS　(CGMGIS)　based　on　the　distributed　component　model.　Since　the　format　and　method　of　the　data　transmission　on　the　network　have　great　influence　on　the　performances　of　WEBGIS,　great　emphasis　is　placed　on　how　to　improve　the　transmission　of　the　data　and　to　create　a　new　communication　mechanism　for　WEBGIS　by　utilizing　the　advantages　of　both　the　DCOM　and　WebCGM　technology　and　introducing　a　new　WEBGIS　data　transmission　and　communication　mechanism.　Meanwhile,　a　new　approach　of　real-time　dynamic　index　is　introduced　focusing　on　the　display　of　the　spatial　typographic　information　at　the　client　end,　in　order　to　solve　the　problem　of　repeated　transmission　of　the　spatial　typographic　information　so　that　the　flow　of　the　network　data　transmission　can　be　cut　down.
