The information published on the WMS GT VI: Map for the prevention of geological hazards 1:25 000 comes from the database of map for the prevention of geological hazards 1:25 000.

The WMS geologic map of Catalonia 1:50 000 is a continuous synthesis created from the information contained in geological maps of the MAGNA serie at 1:50000 scale from Instituto Geológico y Minero de España. The set of geological information is referred to BT50M topographic base valid in 1997.

The WMS Map of hydrogeological areas of Catalonia 1:250 000 is a tool of representation and dissemination of hydrogeological characteristics of the territory and subsoil.

The Orthophoto is a cartographic document that consists of a vertical aerial image which has been rectified in such a way that the same scale is kept in all image surface, being a geometric representation on scale of the terrestrial surface. RGB colour digital images, obtained from a Z/I Imaging DMC digital metrical camera, are used.
