Use of Remotely-Piloted Aircraft as a tool for territorial analysis and management

a study for Urban Land Regularization

Abstract

The management of isolated urban areas is a challenge for the municipal government, especially in small municipalities, whose budget availability is often limited. In this sense, the use of digital aerophotogrammetry, using remotely piloted aircraft (RPA), popularly known as Drones, appears as an alternative of subsidy for urban management, given its low cost, simplified operability and possibility of imaging small areas in a short time. Aiming to assess the feasibility of using this technology, this work aimed to use a RPA (Phantom 4 Pro model) for data collection in an isolated urban area in the municipality of Guararema - SP. The methodology used included the collection of support points in order to attribute positional accuracy to the images, resulting in the construction of georeferenced cartographic material (orthophoto and digital elevation model) and with submetric quality. It was found that the products can be used for land regularization purposes, allowing the vectorization of features such as blocks, lots, buildings, urban infrastructure and vegetation, in addition to the extraction of contour lines. The products fit into the PEC Class A quality classification, with a technical reference scale of 1:1000, reaffirming them as an alternative for updating the municipal registry database and as a source of quality information for the planning and management of urban areas.
