Permeability Map of Spain at scale 1:200.000 digital continuous

The continuous and digital Permeability Map of Spain at a scale of 1:200.000000 is based on the continuous Lithostratigraphic Map of Spain at a scale of 1:200.000 and represents the mapped lithostratigraphic levels grouped by similar permeability values. In order to carry it out, firstly, a legend was drawn up in which a degree of permeability was assigned to each mapped lithostratigraphic unit. Five types of permeability were established: Very high, High, Medium, Low and Very low. The different lithologies were associated into 7 large groups (carbonate, detrital, Quaternary detrital, volcanic, metadetritic, igneous and evaporitic), giving rise to a classification by types of aquifers, established according to the formation processes of each permeability. This map clearly shows the hydrogeological domains with a predominance of calcareous and evaporitic, detritic and crystalline aquifers, highlighting the main peninsular and island structural lines that bring the different groundwater bodies defined into contact with each other. This cartography is adapted to the hydrographic network and the shadow model produced by CEDEX, at a scale of 1:200,000, based on the topographic base, at a scale of 1:50,000, of the Army Cartographic Service. The cartographic information is referenced to coordinates in UTM projection, European Datum, zone 30, except for that corresponding to the Canary Islands, which is referenced to zone 28. The map is made up of the Cartographic Units Information Layer (LPIT) and the external table dat table, which assigns to each lithostratigraphic formation (FH) the degree of permeability as well as the colour of representation. The format of the generated information is Shape file.
