LOPES, T.S.F. Analysis of the applicability of commercial mini-VANT system in the diagnosis of disaster waste generation in Brazil. 2018. 104 f. Dissertation (Master degree) -Faculdade de Saúde Pública, Universidade de São Paulo, São Paulo, 2018. The need to minimize the impacts caused by disasters, and the solid waste generated, motivated the development of methods and practices for the management of disaster residues all over the world. Orbital remote sensing platforms and manned aircraft

The technological development of unmanned aerial vehicles (UAVs), especially low-cost commercial civil models, and the formulation of legislation that deals with their use, has made their application viable in different areas, including precision mapping. In order to analyze the applicability of these platforms in aid of the diagnosis of disaster waste generation, two sets of photographs previously obtained with an "off the shelf" UAV were selected. Then, the processing of these data in PhotoScan was carried out, aiming at the generation of informative maps. It was sought to analyze the capacity of identification, quantification and characterization of the solid residues disposed in the mapped areas. Legal, economic and technical aspects associated to the use of the tool were contemplated, in order to better base the applicability on the question. The results indicated relevant potential of identification and quantification of the residues found, and some limitations in their capacity of characterization. The current legislation, and the economic and technical aspects raised favor the use of commercial mini-VANT for the proposed use, even though in a limited way to disasters where the affected extension is not too extensive. The observance of good practices in the choice of equipment, in the planning and execution of its execution are fundamental for the generation of informative maps containing the positioning, the estimated volume and the estimated composition of the amounts of residues found.
