14. Mapeamento de cobertura vegetal do bioma Cerrado: estratégias e resultados.
ABSTRACT: Mapping Cerrado's vegetation cover is difficult because of its geographical extemt (~ 204,7 million hectares), high seasonality, and high spatial and temporal dynamics of its land use activities. The objective of this study was to map the vegetation cover of the Cerrado biome in the 1:250,000 scale using Landsat satellite imageries from the year of

19. RELAÇÃO ENTRE A COMPARTIMENTAÇÃO GEOMORFOLÓGICA E A OCORRÊNCIA DE ÁGATA E AMETISTA NO MUNICÍPIO DE QUARAÍ-RS / RELATION BETWEEN COMPARTMENTATION GEOMORPHOLOGIC AND THE OCCURRENCE OF AGATE AND AMETHYST IN THE QUARAÍ-RS BRAZIL.
The study of geomorphology takes place in the geographical science with the aid of other sciences such as geology. In these studies, the relief is a key element in the understanding of the relationship between the physical aspects (lithology, soil, vegetation, hydrography, climate, etc.) and the activities of human beings. Thus, to understand the interfaces

20. Análise de imagens do satélite ALOS PALSAR (Banda L, modo polarimétrico) para discriminação de coberturas de terras no Distrito Federal
Land cover maps are important source of data for environmental monitoring, biodiversity conservation, social, economic and environmental zonning, and local and global climatic changes, among other activities. In the Federal District of Brazil (FD), land cover mappings have been obtained from optical images. However, radar data are valuable alternative for th

23. Uso de imagens ALOS/PALSAR multipolarizadas para detecção de incremento de desflorestamento na Amazônia / Use of multipolarized ALOS/PALSAR image for detection of increment of deforestation in the Amazon
The Amazon forest is a region of rainforest, which has about 5,4 million square kilometers, and with great biodiversity of species on the planet. However, its traditional model of occupation has lead to significant levels of increase of deforestation in the brazilian Legal Amazon. Through remote sensing, these areas can be constantly monitored, offering rate
