Integration of high resolution optical satellite imagery and geophysical survey for archaeological prospection in Hierapolis (Turkey)

An in-depth analysis of the site of Hierapolis (Turkey) has been carried out using high resolution remotely sensed imagery integrated with geophysical survey and direct field data in order to detect evidence of archaeological features and environmental setting. High resolution panchromatic and multispectral images acquired by different satellites were used in this study. These images, acquired also in stereoscopic configuration, were digitally processed and visually interpreted. Geophysical data were collected in some areas of interest using different surveying methodologies (electric, radar). Besides the important scientific implications, the integration of remote sensing and geophysics in archaeology provided a useful tool for the optimization of landscape and cultural heritage management. All data collected were integrated in a Geographic Information System (GIS) to produce comprehensive maps of the site depicting archaeological and environmental features.
