O presente artigo aborda o uso dos sistemas de informacao geografica no mapeamento de queimada em uma area rural do municipio de Agua Comprida/MG. O objetivo principal foi mapear apenas os remanescentes de mata nativa atraves de imagens de satelite do sensor OLI/Landsat 8 em dois momentos distintos: julho de 2014, anterior ao episodio da queimada, e agosto de 2014, posterior a mesma, tendo em vista avaliar o danos causados. Aplicou-se o classificador por maxima verossimilhanca, gerando dois mapas tematicos para os dois periodos e, atraves de tecnicas de geoprocessamento, verificar a area de mata nativa danificada pela queimada. O mapeamento inicial, de julho de 2014, indicou que a area total afetada pela queimada era de 36,32km², dos quais 5,32km² eram de mata nativa. O mapeamento feito sobre a cena de agosto de 2014 indicou uma perda de 1.66km² de mata nativa. O procedimento aqui adotado e exploratorio e serve apenas como um indicador para o monitoramento florestal. Abstract This article discusses the use of geographic information systems mapping burned in a rural area of the municipality of Agua Comprida/ MG. The main objective was to map only the remnants of native forest using satellite images of the OLI / Landsat 8 at two different times: in July 2014, prior to the episode of the burning, and August 2014, later the same, in order to assess the damage. Applied the maximum likelihood classifier by generating two thematic maps for the two periods and through geoprocessing techniques check the area of native forest damaged by fire. The initial mapping of July 2014 indicated that the total area affected by fire was 36,32km², of which 5,32km² were of native forest. The mapping done on the scene in August 2014 indicated a loss of 1.66km² of native forest. The procedure adopted here is exploratory and only serves as an indicator for forest monitoring.
