ABSTRACT

An integrated analysis of spatial and satellite data has been applied on an area of the province of Teramo in Abruzzo region, Italy. Two case studies are presented: one on the gullies of Montefino, as an example of natural heritage at risk, and the second case concerns the municipality of Bisenti, as an example of historic centre at risk.

Geomatic methodologies have been used for a preliminary analysis of the study area. Based on the cartographic data, hazard maps were overlaid to high-resolution satellite images, showing a high risk for cultural heritage. The integrated analysis is proposed as a monitoring tool to safeguard the territory and the historical and natural heritage by providing knowledge of both their conservation status and relations with the natural risk (landslides, floods, earthquakes). The geomatic techniques have been applied using the overlaying of spatial data interpreting high-definition satellite images and vector data from local archives (PAI, IFFI, Corine Land Cover). The results are an integrated analysis control tool for the safeguard of our heritage. The information obtained through integrated analysis of spatial data and satellite have been verified by field analyses of geo-lithological and petrographic characteristics of the rocky outcrops. The data processing allowed to create new thematic layers, and especially to query a spatial data in connection with others. The integrated analysis is then a safeguard tool for monitoring the conservation status of the territory and getting knowledge of its relationships with cultural heritage, landscape and historic center seen as a whole and not as a set of individual monuments.
