Combined application of pansharpening and enhancement methods to improve archaeological cropmark visibility and identification in QuickBird imagery: two case studies from Apulia, Southern Italy

All methods were evaluated on QuickBird imagery acquired in the Tavoliere plain (Apulia, Southern Italy) on May 27th, 2006. In particular, cropmarks generated by two buried ancient settlements were considered. For one of these test sites, results of a high resolution ground magnetic survey, carried out for other aims, were also employed to further assess the validity of information extracted by the proposed workflow.
