IGME - Lithostratigraphic Map of Spain at scale 1/200000

The continuous lithostratigraphic map of Spain in digital format at a scale of 1:200,000 represents the cartographic units characterised mainly according to lithostratigraphic and hydrogeological criteria. The criteria maintained to consider their cartographic representation are to maintain those units that present an important lithostratigraphic development, both for their representation and their singularity, also incorporating those that show a high hydrogeological interest, either because of their own lithological nature (high permeability) or because they are considered to form an essential part of the definition of the aquifer. The contacts between the cartographic units represented were normal, unconformable and intrusive contacts. Faults, thrusts and folding structures are represented. Thus, a continuous map has been obtained in digital format, in which there are still areas with a higher density of cartographic information than others, either because they come from synthesis maps made with less general criteria than these, or because for their preparation, smaller scale cartographies (e.g. 1:50,000) have been used, thus obtaining a much richer and more detailed cartography. This map is the basis for the permeability and hydrogeological maps of Spain at a scale of 1:200,000 continuous and in digital format. This cartography is adapted to the hydrographic network and the shadow model made by CEDEX, at a scale of 1:200,000, from the topographic base, at a scale of 1:50,000, of the Army Cartographic Service. Given the scale of detail of this cartography, the availability of the entire national territory, and the impossibility of appreciating the detail it possesses at small scales, the information is only visualised from the visualisation scale indicated in the Capabilities file.
