Photo Interpretation and GIS as a support tool for Archaeology

This work presents photo interpretation integration techniques of high resolution aerial photographs and satellite images. Through the use of this methodology, it is possible to identify Dolmens located in the Center Alentejo - Portugal, and recover archaeological information. From the observation of dolmens it was perceived the shape of these objects visualised in vertical images. The use of Remote Sensing techniques in conjunction with ArcGIS allowed to confirm and to know the interpretation keys of these monuments. This feature keys allow to identify and recognise sites already identified as well as new buildings.
