Multi-temporal archaeological analyses of alluvial landscapes using the photogrammetric restitution of historical flights: a case study of Medellin (Badajoz, Spain)

► Several Digital terrain models from historical flights were obtained by restitution procedures. ► DTM analysis and photo interpretation revealed important changes in topography and land use of the area. ► We can map the degree of surface alteration in the last half century. ► Quantification of change is useful for assessing reliability of archaeological survey. ► Results are also a valuable tool for heritage management and future territorial planning.
