Abstract

The use of camera operating in the 8-12 µm range of electromagnetic wave spectrum, prove to be satisfactory in various sectors of the engineering geology. The results of some surveyings carried out by means of fixed stations on the land have been presented. The interpretation of the thermography which have been obtained is related to the meaning which is likely to be ascribed to the temperature distribution on the surface of the investigated bodies. In fact, the system shows in the form of shades of gray or of false colour the thermal energy radiated and reflected by the observed bodies. Starting from the most traditional applications concerning the census of submarine springs, but still prerogative of the most sophisticated systems based on the use of airborne multi-spectral scanners, the easiest thermovision system, which is also likely to be used on platforms installed on small aircraft, may stretch the applications range of remote sensing techniques to various field of the engineering geology. Besides the low cost and readiness of the survey, the thermovision system, used from fixed stations, allows to obtain images in the scale of the desired detail.Examples which have been presented refer to the location of submarine springs flowing along a part of the coast near Polignano (Bari, Apulia region) and near Maratea (Potenza, Basilicata Region), the observation of a landslide near Brindisi di Montagna (Potenza, Basilicata region). In the discussion of data resulting from thermographies taken on the above said objectives one can even realize factors which may negatively affect the image interpretation such as, for instance, the disturbance caused by vegetation to the temperature distribution on the land surface.
