Georreferenciamento de árvores em vias públicas com imagens esféricas nos bairros Jardim Cidade Nova e residencial Morumbi na cidade de São Sebastião do Paraíso/MG

Abstract

Urban afforestation contributes to the well-being of the urban population, having a direct impact on thermal comfort, improving air quality, reducing noise and visual pollution. Indirectly, urban afforestation can contribute to improving the physical and mental health of the urban population. On the other hand, the presence of urban afforestation can lead to accidents, bringing risks to the population, especially when the vegetation is in contact with electrical transmission lines or when there is no proper management. This proper management of urban vegetation can enhance the benefits and also reduce the risk of accidents. However, proper management is only possible based on data that allow the public authorities to become aware of the current situation of the trees present on the roads. Several techniques can be used to acquire these data and in this work a land mobile mapping system with a spherical camera was used, in the Jardim Cidade Nova and Residencial Morumbi neighborhoods of the municipality of São Sebastião do Paraíso/MG. 240 trees were georeferenced and in comparison with the mapping performed with an orthophoto of approximate pixel size of 5cm, the discrepancy between the two georeferencing was 2.461 m, which shows the feasibility of this type of georeferencing.
