1:200,000 continuous digital hydrogeological map of Spain (IGME)
Description
The continuous Hydrogeological Map of Spain in digital format at 1:200,000 scale is made from the Lithostratigraphic and Permeabilities Map of Spain, continuous at 1:200,000 scale and represents the mapped lithostratigraphic levels, grouped by range of permeabilities and associated lithologies, and represented with a certain color and tone, so that it is possible to visualize on the map the areas associated with the different aquifers.
Blue colors represent porous aquifers, cracked or karst green aquifers and brown ones represent impermeable or low permeability formations. Productivity is represented by tone, in the case of permeable formations, dark tones indicate greater productivity and in the case of impermeable formations indicate greater impermeability.
For the elaboration of the Hydrogeological Map, once it was verified that on the Lithostratigraphic Map and Permeabilities of Spain were differentiated cartographically the formations that constitute the main aquifers, we proceeded to the elaboration of a hydrogeological legend, grouping them according to their permeabilities, geometry, hydraulic relationship and hydrogeological functioning. This work was carried out taking into account the existing information of the different aquifers in Spain as well as the groundwater bodies defined in accordance with the Water Framework Directive (WFD).
The continuous Hydrogeological Map of Spain in digital format at 1:200,000,000 scale arises from the need for a continuous map of the entire national territory on which to capture the information and distribution of groundwater bodies (m.a.s). This cartography is adapted to the hydrographic network and the shadow model made by CEDEX, at 1:20,000 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 Hydrogeological Map consists of a polygonal layer of cartographic units (LPLIT) and the external tables Hidro.dat and Descrip_hidro.dat . The format of the generated information is Shape file.
