Aplicación de los Sistemas de Información Geográfica (SIG) a datos hidrogeológicos del acuífero de La Aldea (Gran Canaria)

Abstract

Geographic Information Systems (GIS) have been used to organiza and represent hydrogeological Information of La Aldea aquifer, West of Gran Canaria island. Data comes from previous works carried out in the área by the Hydrogeological Group of Las Palmas University. Different kind of Information (administrative, constructiva, chemical, etc.) coming from 382 wells of the área has been represented by means of relating cartographic maps with the hydrological Information stored in a Microsoft Access datábase. Furthermore, some hydrochemical parameters have been analyzed in arder to determina the Influence of lithologies in tha chemical composition and the productlvity of the watars, as well as the spatial dlstrlbution of thase valúes for a batter understanding of the general dynamics of the aquifer. The GIS project "Aldea" intends to improve the accessibility to scientific Information and the possibilitles of its management and monitoring by the Water authorities of the island.
