Satellite Remote Sensing for Archaeology and Management of Landscape

Two Italian research Institutes have developed an advanced approach for processing data from multispectral satellite images at very high spatial resolution. The methodology is applied in the field of archaeological prospection in order to identify buried archaeological structures and sites and to manage archaeological sites. Data obtained can give information for the protection of landscape of historical interest. The two Institutes are looking for technical co-operation and financial resources.

Description

During the last century, aerial photos have been the most common remote sensing data source used in the field of archaeological investigations. The current availability of Very High Resolution (VHR) satellite images can provide new perspectives in the field of archaeological prospection. The main advantages of VHR satellite images compared to aerial photos, are the synoptic view and a more fruitful dataset thanks to its wider spectral capability. The integration with other datasets, such as hyperspectral airborne images, Laser Imaging Detection and Ranging (LIDAR) and Synthetic Aperture Radar (SAR) airborne and satellite data, allow to achieve significant improvement in the data analysis and interpretation process, especially in complex environmental contexts (such as desert, forest covered areas, etc.) Concerning the VHR satellite, the proposed data processing takes advantage from data fusion, edge enhancement, edge detection and pattern recognition techniques. This approach allowed us to discover archaeological remains of different historical periods and site typologies (Neolithic settlements, Etruscan remains, Roman centuriations, medieval villages, paleoriverbeds, Precolombine earthen monuments and settlements).
