MapServer is used to release Web Map Service (WMS) referring the international specifications and standards. The combination of data and MapBox tiles are used by LeafletJS to generate the GIS map view. When the app page is opened, the GIS map could be visualized as the map service.
When the online application opened, the documents and information of basic geography, hydrology and flood disaster are classified and sorted by label control. Additional links for related pages are listed in the app page for user to get more readings.
