According　to　the　business　requirements　of　distribution　network　planning,　this　paper　deeply　studies　the　existing　simplified　display　algorithm　of　distribution　network　in　GIS,　constructs　the　distribution　network　model　based　on　geographic　information　technology,　develops　the　functions　of　supporting　storage,　display　and　display,　and　the　function　module　of　professional　map　editing　for　distribution　network　planning.　The　concept　of　spatiotemporal　data　and　its　application　in　GIS　are　innovatively　put　forward.　The　display　research　based　on　the　status　quo　and　the　analysis　and　management　technology　of　distribution　network　structure　under　planning　state　are　carried　out.　The　spatiotemporal　representation,　spatiotemporal　evolution,　and　comparison　of　power　grid　are　realized.　The　geographic　image　elements　are　matched　and　associated　with　equipment　parameters　to　realize　the　integrated　modeling　of　map　and　power　grid,　realize　the　penetration　function　from　the　map　to　equipment　parameters　and　power　grid　indicators,　and　support　the　diagnosis　and　analysis　of　power　grid-related　indicators.　Finally,　a　three-dimensional　power　map　with　time　dimension,　space　dimension,　and　attribute　dimension　is　constructed　to　provide　geographic　environment　and　equipment　parameter　data　for　power　grid　planning,　site　selection,　and　line　selection.　©　Published　under　licence　by　IOP　Publishing　Ltd.
