Individuazione e ricostruzione di siti archelogici attraverso l'uso integrato di tecniche di remote sensing

This research utilizes and develops high resolution satellite remote sensing applications with the aim of detecting and interpret archaeological sites. Other not invasive technologies have been applied together with remote sensing, allowing to verify and integrate remote sensed data, such as geophysics, digital photogrammetry, Geographic Information System (GIS) and Global Positioning System (GPS). Two case studies have been examined to this purpose. The first investigates Uşaklı Höyük site, in Turkey. After several processing, the fusion of two images acquired by two different satellite sensors supported the individualization of several anomalies. The comparison and the integration of data coming from geophysical prospection and surface surveys allowed to confirm and to improve the interpretation results coming from remote sensed data. Besides, a stereo couple of satellite images allowed the creation, through digital photogrammetric techniques, of a new topographic-archaeological map at a middle-large scale. The map will be useful to manage, within the GIS, the produced data and those that will be collected in the future and it will lead analyses on micro- and macro-scale. By means of photogrammetric techniques the Digital Elevation Model (DEM) and the ortophoto of the area have been also crated. The second case study is related to Vésztő Mágor tell site, in Hungary. Satellite photointerpretation analyses have been carried out and integrated with multitemporal aerial photos and geophysical prospections such as magnetic and Ground Penetrating Radar (GPR), allowing to detect a remarkable quantity of archaeological anomalies. Particularly, a specific algorithm has been developed, aimed to detect elliptical elements such as tell. Besides, in an experimental way, a methodology able to extract contemporary information belonging to satellite images and geophysical images data has been developed. For this scope, the geophysical data have been managed such as different layers of a satellite image. The high resolution remote sensing has shown to be, for these test sites, an effective instrument able to furnish preliminary information detailed enough to address other kinds of prospection and/or excavations. The integration with other not invasive techniques of archaeological prospection has demonstrated to strengthen such results. It is advisable that the research continues on developing automatic processes of anomalies individualization and new kinds of data integration.
