IDE-CHG offers geographic information referring to hydrographical demarcation territory. This information has been produced mainly by the organization although there are other interesting data that have been published by external sources. Here metadata play a fundamental role when it comes to identifying origin and quality of data.

In general terms IDE-CHG serves the following geographic information using several routes:

• Monitoring Point
  • Stream-gage stations.
  • Automatic System of Hydrologic Information.
  • Surface water quality monitoring stations – SAIH.
  • Automatic System of Quality of Waters.
  • Groundwater quality monitoring stations.
  • Springs.
  • Piezometers .
  • Rain-gage stations.

• Hydraulic infrastructures

Besides being able to consult this information using the cartographic viewer, the citizen has also access to it from the OGC services. As well part of these data are available in the download area under several formats: .shp, .kmz and .dgn.

In the download area there is also a series of A3 theme maps available to users in .pdf and .jpg formats.

Every time that new information is incorporated to the IDE-CHG, the ‘Novelties’ section will be updated.
