Utilização de imagens espectrais de média resolução espacial na análise da expansão urbana do município de Betim (RMBH) por meio de modelo de mistura

This study prupose the mixing model aplication as a methodology for urban expansion interpretation using medium spatial resolution images - in this case, Landsat 5 TM with 30m spatial resolution; as well the comparasion of this model with a visual classification for urban expansion regions. The comparasion results between the mixing model and the visual classification was linear, indicating that the mixing model is viable to the analisys of urban expansion.
