Spectral Classification Procedure to Map Asbestos-cement Roofs – Medical Diagnosis

  • Rating12345

This abstract describes a systematic procedure for analysing corrugated asbestos-cement roofing sheets with Remote sensing test, Open  Source data and other analysis (e.g. chemical and medical test) in order to analyse the asbestos fiber air dispersion that can cause lung cancer. To develop this procedure, we should implement test field and laboratory measurements and gathered airborne hyperspectral data covering two industrial test areas in Italy. Laboratory analyses of asbestos-cement samples representing various levels of deterioration allowed for identifying their optical characteristics using portable field spectrometers and remote sensing data. Suitable MIVIS spectral regions were used in a spectral classification procedure to map asbestos-cement roofs. 

The detected roofs were further analyzed using the obtained linear regression lines to estimate surfacing asbestos fiber abundance, using the MIVIS TIR range at 9.44μm, selected by means of the asbestos-cement detection limit analysis. The results showed that a hyperspectral scanner with suitable operational characteristics allows for good clustering of AC roofs as a function of their deterioration status. Therefore, semi-automatic choice of scale-dependent features for satellite image classification could implement this analysis.

This analysis can furnish local authorities with an efficient, rapid and repeatable environmental mapping procedure that can provide information about the location of hazardous AC roofing sheets and can support medical diagnosis. From the point of view of statistics the diagnostic procedure involves classification tests. The participation and cooperation of local authorities, Research Centres, Universities and SMEs will be a determining factor in fulfilling its objectives.

Local authorities construct, operate and maintain economic, social and environmental strategies, oversee planning processes, establish local environmental policies and regulations (e.g. D.M. 06/09/1994 and D.M. 20/08/1999) and assist in implementing national and sub-national strategic policies. As the level of governance closest to the people, they play a vital role in educating, mobilizing and responding to the public to promote sustainable development.
