Permeability Map of Spain at 1:200,000 Continuous Digital Scale (IGME)
Description
The continuous Permeability Map of Spain in digital format at 1:200,000 scale is made from the continuous Lithostratigraphic Map of Spain at 1:200,000 scale and represents the mapped lithostratigraphic levels grouped by similar permeability values.
For its realization, in the first place a legend was made in which a degree of permeability is assigned for each mapped lithostratigraphic unit. Five types of permeability were established: Very high, High, Medium, Low and Very low. The different lithologies were associated in 7 large groups (carbonate, detritic, detritic of the quaternary, volcanic, metadetritic, igneous and evaporitic), giving rise to a classification by types of aquifers, established according to the formation processes of each permeability In this map it is possible to distinguish perfectly the hydrogeological domains with predominance of calcareous and evaporitic, detritic and crystalline aquifers, highlighting the main peninsular and island structural lines that put in contact the different groundwater bodies that have been defined. This cartography is adapted to the hydrographic network and the shadow model made by CEDEX, at 1:200,000 scale, from the topographic base, at 1:50,000 scale, of the Army Cartographic Service. The cartographic information is referred to coordinates in projection UTM, European Datum, spindle 30, except that corresponding to the Canary Islands that is referred to spindle 28. The map consists of the Cartographic Units Information Layer (LPIT) and the external Perme.dat table, which assigns to each lithostratigraphic formation (FH) the degree of permeability as well as the color of representation. The format of the generated information is Shape file.
