GeoServices: geoscientific data for re-use

BRGM’s geoscientific data can be re-used readily and simply thanks to a range of interoperable services (OGC, KML, INSPIRE)

BRGM offers free public access to all data for which it is fully or partly responsible. These are the vast majority of data available through the InfoTerre portal.

Data is available for re-use via web services with functions allowing easy use of information on geology, natural and industrial risks and extracted materials.  

A full range of services

Thanks to the range of services offered by BRGM, users can access drilling data from the subsoils databank, harmonised geological maps, subterranean cavities and much more. Users can also provide access to these services and data from their own internet projects, office technology, modelling applications, etc.

The standards used are as follows:

  • KML: OGC standard used by Google tools to access data from Google Earth or Google Maps. Allows users to incorporate BRGM data into their own mapping applications.
  • OGC Web Map Service (WMS), version 1.1.1 and 1.3.0. Standard enabling users to display data in compliance with INSPIRE requirements. These services can easily be incorporated into users’ cartographic web sites (OpenLayers, ESRI, etc.) or professional software (e.g. MapInfo, ArcGis, QGIS, etc.).
  • OGC Web Feature Service (WFS), version 1.0.0. This standard gives access to the data and in particular to downloads of public data for re-use, via the GML access format. These services are compatible with professional software such as MapInfo, ArcGis or Qgis.
  • Web Map Service with tile caching (WMS-C) is an extension of the WMS format for accessing data as a cached tile set to accelerate the display. Web sites using WMS-C-compatible software components can optimise geological data displays (e.g. OpenLayers).

Interoperable services complying with INSPIRE requirements

The services offered by BRGM cover all BRGM geoscientific information. 

The data are interoperable subject to compliance with the standards of the Open Geospatial Consortium (OGC) and with the spirit of the implementation rules of the EU  INSPIRE Directive on access to information on the environment.

BRGM geological maps on Google Earth

Users can access BRGM’s geological maps through Google Earth, which displays satellite imagery and many other layers of 2D and 3D data.

To see the Geological Map of France in 3D on Google Earth:

  • Make sure that Google Earth is installed on your computer, with the .kml and .kmz file extensions.
  • Click on the KML link to the geological map you want to see.

Les cartes géologiques du BRGM peuvent être visualisées dans l’application Google Earth, logiciel qui permet une visualisation de photographies satellites et de nombreuses autres couches de données en 2D et 3D.
