Mapping of ground fires in the Emas National Park, Goiás: 1973-1994


The project has the objective of identifying and mapping the ground fires which occur in the Emas National Park (PNE), GO, since 1973, to provide information for the study of the role of fire in this region of cerrado (wooded savanna). For this purpose, satellite images will be used for the Landsat systems, sensor MSS (1973-1983) on the scale 1:250,000 and TM (1984-1994) on the scale 1:100,000. With the aid of records available in the park, to be obtained from theBrazilian Institute of the Environment and of Natural Renewable Resources (Ibama), we will analyze anual images from that location and, when the occurrence of ground fire is noted, the limits of that fire will be mapped. These maps, produced on the basis of visual interpretation of the images, will be managed through the Geographical Information System (GIS) of the National Institute for Space Research (Inpe), thus creating an information plan (IP) for each ground fire event recorded. Finally, all the IPs will be superimposed in the GIS environment, creating maps for temporal and spatial analysis of the areas affected by ground fires in that park. (AU)
