Análise da temperatura de superfície em ambientes urbanos: um estudo por meio de sensoriamento remoto no município de Goiânia, Goiás (2002 – 2011)

Among the urban environmental impacts that need to be considered in the process of land use, is the change in the thermal field induced by the replacement of the natural land cover, followed by the appropriation of these spaces for anthropic activities. Within this scope, the present work, conducted...
