Datagov Opendata Platform

The Water Resources Agency and its affiliated agencies provide relevant point information for various river cross-section points for use by civil organizations, groups, or academic units engaged in projects commissioned by government agencies. This dataset is linked to a Keyhole Markup Language (KML) file list, a markup language based on XML syntax standards developed and maintained by Keyhole, a subsidiary of Google, for expressing geographical annotations. Documents written in KML language are KML files, using the XML file format, and are applied in Google Earth-related software to display geographical data (including points, lines, areas, polygons, polyhedra, and models). Many GIS-related systems now also use this format for the exchange of geographical data, and the fields and encoding of this data are all in UTF-8.
