Thickness of Maspalomas dune field has been determined by combination of several geophysical techniques. Present high resolution topography of sand sheet, dune and interdune areas have been obtained from a fotogrametric flight in January’06with a 1:3,500 scale. Thus, a digital terrain model (MDT) with a 1:500 scale and 4x4 m grid have been designed.Geological contacts between aeolian sand and lower materials have been determined from 4,505-m lines of Seismic refraction and electrical resistivity tomography.
