1. Land use and water quality in watersheds in the State of São Paulo, based on GIS and SWAT data
Resumo O uso e ocupação do solo influenciam a qualidade e a disponibilidade de água, devendo ser considerados numa gestão integrada dos recursos hídricos e no planejamento das bacias hidrográficas. Ferramentas de geoprocessamento têm sido utilizadas para classificação do uso do solo e combinadas com modelos hidrológicos para avaliação do impacto

2. Mapping and characterization of intensity in land use by pasture using remote sensing
RESUMO A demanda atual por alimentos tem sido atendida por meio da exploração das reservas naturais. O Brasil apresenta 26% da sua extensão ocupada por usos agropecuários, sendo 62% desses, pastagens. Pastagens degradadas apresentam maior intensidade de uso da terra do que pastagens bem manejadas, levando à maior degradação do meio ambiente. Os sistem

3. Satellite Spectral Data on the Quantification of Soil Particle Size from Different Geographic Regions
ABSTRACT: The study of soils, including their physical and chemical properties, is essential for agricultural management. Soil quality must be maintained to ensure sustainable production of food and conservation of natural resources. In this context, soil mapping is important to provide spatial information, which can be performed using remote sensing (RS) te

4. Evaluation of deciduous broadleaf forests mountain using satellite data using neural network method near Caspian Sea in North of Iran
ABSTRACT During the recent decades, deciduous forests have been molested by human intervention. Easy access, abundance and diversity of valuable forest products have led to increased population density, creating new residential areas and deforestation activities. Revealing changes is one of the fundamental methods in management and assessment of natural reso

5. Caracterização ambiental e estimativa da produção de cargas difusas da área de drenagem da represa de Itupararanga, SP / Environmental characterization and estimative of diffuse pollution of Itupararanga watershed, SP
The use of satellite images has improved the study of the land use dynamics. Land cover mapping have become fundamental tools in the assessment of landscape changes caused by human action and its influence on regional and urban planning. Computation tools such as Geographic Information Systems and hydrological models have supported these findings. The hydrol

6. Mapeamento de corredores ecológicos na APA Fernão Dias - MG a partir de técnicas de geoprocessamento e análise espacial / Mapping of ecological corridors in the Fernao Dias EPA - MG from techniques of geoprocessing and spatial analysis
A fragmentação florestal, resultante do processo de substituição da cobertura vegetal nativa por áreas antrópicas, é responsável pela redução do tamanho das manchas florestais e é a principal causa da extinção de espécies da fauna e flora nativas. A implementação de corredores ecológicos que conectam fragmentos de habitat configura-se como u

7. Uso das terras e legislação ambiental: a microbacia do Ribeirão Sapé no município de Caldas Novas (GO) / Land use and environmental legislation: the micro-basin of the municipality of Ribeirão Sapé in Caldas Novas (GO)
From the 1930s Brazil created many laws to protect the natural resources. But with the implantation of incentive programs which aim the economic growth at any cost, with modern farming practices and the expansion of agriculture and cattle raising, great losses occurred to the preservation and conservation of the natural resources. The driving question for th

8. MAPEAMENTO DE ÁREAS ÚMIDAS E BANHADOS NA MICROBACIA DO RIO AMANDAÚ, REGIÃO NOROESTE DO RIO GRANDE DO SUL / MAPPING OF MOISTURE SOIL AND WETLANDS IN THE WATERSHED OF THE AMANDAU RIVER, NORTHWEST REGION OF RIO GRANDE DO SUL
The wetlands are one of the worlds most productive places, with high rates of biological diversity and also highly impacted. In this context, this project was aimed at mapping the Wetlands Ecosystems present in the soil moisture in the watershed of the Amandau River (Watershed U30), using orbital images and clinographic terrain maps. This research was struct

9. Desenvolvimento de metodologia em SIG para zoneamento ecológico: estudo de caso da Bacia Ribeirão do Gama-DF.
ABSTRACT: The permanent preservation areas were created to protect the environment, decreasing processes as erosion often caused by anthropic interferences. The Brazilian Forest Law stablished criteria to the delimitation of these areas. An area zoning presents special areas where permanent preservation areas are inclued. This way, in the present paper was p

10. Mapeamento de unidades experimentais com GPS: caso de estudo da Embrapa Cerrados.
ABSTRACT: The major objective of this work was to map the research units and the infrastructure available in the Embrapa Cerrados experimental farm in Planaltina, Federal District. More than 190 identities were observed and mapped through the use of GPS portable receiver with an accuracy of about five meters. The UTM coordinates obtained by the GPS were stor

11. Pedoforms mapping at the Águas Emendadas ecological station, Distrito Federal, Brazil.
The great urban and rural development of the Distrito Federal (Federal Administrative District) in Brazil over the last 50 years has led to disordered land use and land occupation. To assess the current environmental scenario, detailed surveys of the available natural resources, especially soils, are required. The objective of this work was to evaluate the s
