Base map tables - Giswater/giswater_dbmodel GitHub Wiki

---

Description:

The base map group consists of tables related to address and raster data. Address data are used for searching the exact location on the map and, in case of water supply, it's also used to situate the source of the minimum cut process. Raster data, apart from acting as a backgroud image, may be used to capture the elevation of the network elements. Giswater allows two ways of storing base map data - inside a schema, which is recommended in case of having just one project, or by creating a common 'utils' schema which shares data of addresses and rasters between both water supply and urban drainage projects. In this case the tables inside utils schema has the same names as those listed below, but without 'ext_' prefix and inside working schema appear new views with the prefix.
