Lithological and structural mapping of the Sorbas area (Baetic Mts., prov. Almería, Spain) based on remotely sensed images

Abstract

Digitally enhanced Landsat 8 images were applied for geological mapping of Sorbas Area in Almeria Province, SE Spain. The terrain without abundant vegetation, with semiarid landscape is promising for remote sensing research. For this study multispectral images were processed and analysed. On the basis of the classification, main lithological units were distinguished, with overall agreement with the reference data of 15,127%. The results are subject to discussion about the utility and limitations of remote sensing method on the study area. Further complimentary studies may be useful. Finally, problems encountered during classification must be factored into the overall accuracy.
