USE OF REMOTELY PILOTED AIRCRAFT (RPA) FOR THE PREPARATION OF RISK AREA MAPPING

A CASE STUDY OF DISTRICT CACHOEIRINHA, VIÇOSA - MG

Abstract

Improper misuse and parceling of land, such as: the construction of houses in topographically unsuitable places, due to the lack of planning or public public policies, constantly causes human and infrastructure losses in several cities in Brazil. The identification of areas at risk of landslides and flooding, using precision equipment, can contribute to the advancement of research related to this topic, generating more efficient public policies. In this sense, this research identified and analyzed as risk areas in the Cachoeirinha neighborhood, in Viçosa, Minas Gerais, with the use of equipment such as: GNSS / RTK (Real Time Kinematics), to collect control points, Pilot Aircraft Remotely - RPA, for collection of images, methodologies and tools of the Geographic Information System. As a final result, the mapping of areas vulnerable to risk is obtained, elaborated by the use of multicriteria analysis, with the variables: slope, density of buildings, distance from the watercourse and land use and coverage, determined in the field. Material was produced that can serve as a reference for future research and to provide subsidies for the definition of public policies that contribute to solving this serious problem in urban areas.
