Developing expeditious methodology for mapping asbestos-cement roof coverings over the territory of Lazio Region

Abstract

This paper reports the results of a research activity over the territory of Lazio Region for the mapping of asbestos-cement (AC) roof coverings in conformance with Law D.M. 101/2003. Through combining data retrieved from Multispectral Infrared Visible Imaging Spectrometer (MIVIS) classification by Spectral Angle Mapper (SAM) and Regional Technical Map (RTM), it was possible to accurately map out the area of interest in reduced time. The maps acquired by applying the Minimum Bounding algorithm were then compared with the Classification and RTM Intersection. The results obtained so far were validated by means of field measurements and can be considered as satisfactory. However, we think it is necessary to highlight how combining MIVIS and RTM data, and using many different software packages, have contributed to give concrete answers to those environmental issues hardly to be investigated and, to open up new, significant prospects for territorial surveys.
