Telerilevamento di aree archeologiche mediante dati iperspettrali MIVIS” (Remote sensing of archaelogical areas using hyperspectral MIVIS data)

2004

The aim of this study is to examine the relationship between physical parameters and the spatial distribution of buried archaeological structures, using data acquired by the airborne hyperspectral sensor mivis in the visible, near infrared and thermal infrared wavelengths. The study areas are the territories of Halaesa, an important city in the Hellenistic-Roman period, and the Punic city of Mozia in Sicily. The influence of buried structures on thermal-radiative behaviour has been investigated using three parameters: Normalized Difference Vegetation Index (ndvi), thermal inertia, and Thermal Balanced Gradient. These techniques are shown to be particularly effective in identifying surface p…

Telerilevamento e GIS per la valutazione e il monitoraggio delle isole di calore in ambiente urbano

2017

The techniques of spatial analysis and Remote Sensing represent an useful tool for the knowledge and the study of the Urban Heat Island phenomenon (English acronym UHI). In this study, among the different causes that lead to the generation of the event, those regarding physical features of the surface and the presence of different land use/cover such as: the high cover of urban areas and the lack of green areas have been examined. The Remote Sensing techniques allow to create maps of the land use/cover, then, in order to estimate the different in temperature due to the distance to the vegetation, the temperature of the bodies already tested have been compared with a thermal map.
