A　map　is　the　most　intuitionistic　and　effective　visual　carrier　of　spatial　information.　From　the　viewpoints　of　spatial　query　and　spatial　analysis　of　geographical　information　system　(GIS),　this　paper　discusses　the　human-machine　interaction　process　of　cartographic　visualization,　analyzes　the　main　functions　of　the　interactive　visualization　interface,　illustrates　three　modes　of　interactive　visualization　query　and　the　relationships　between　the　modes　and　the　interface,　presents　a　framework　for　the　spatial　analysis　of　interactive　visualization　system,　and　describes　the　relationship　among　four　basic　functions　of　spatial　analysis　in　the　spatial　analyzing　framework,　such　as　the　selection,　the　manipulation,　the　exploration　and　the　confirmation.　Moreover,　a　prototype　system　of　map-based　interactive　visualization　is　designed　and　implemented,　the　case　study　illustrating　the　practicability　of　the　system.
