1. Annual cropland mapping using data mining and OLI Landsat-8
RESUMO No Estado do Paraná, Brasil, não há grandes mudanças nas áreas cultivadas com culturas anuais, principalmente devido a leis ambientais que não permitem expansões para novas áreas. Há grande contribuição das culturas anuais para a demanda doméstica de alimentos e econômica nas exportações. Assim, a área e distribuição das culturas anu

2. MODELING AND SIMULATING LAND USE/COVER CHANGE USING ARTIFICIAL NEURAL NETWORK FROM REMOTELY SENSING DATA
ABSTRACT Increasing population, mobility and requirements of human beings have significant effects on the dynamics of land use and land cover. Today, these impacts need to be understood and analyzed for the applicability of decision support systems, which are an important tool in the management of natural resources, urban and rural areas. The aim of this stu

3. Managing agricultural phosphorus to minimize water quality impacts
ABSTRACT Eutrophication of surface waters remains a major use-impairment in many countries, which, in fresh waters, is accelerated by phosphorus (P) inputs from both point (e.g., municipal waste water treatment plants) and nonpoint sources (e.g., urban and agricultural runoff). As point sources tend to be easier to identify and control, greater attention has

4. 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. Análise da Paisagem da Bacia Hidrográfica do Rio Tijucas, SC: Proposta de Áreas Prioritárias para um Sistema de Unidades de Conservação
The analysis of use and land cover is one of the key steps for conducting the strategic planning of conservation of a watershed. This work aims to analyze the landscape of the River Basin Tijucas for purposes of proposed priority areas for implementation of conservation, using as tool the Geographic Information System (GIS), aiming to provide support for pro

7. 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

8. Estoque de carbono nos solos da bacia do Rio Araguari-MG: estimativas, modelagem e cenários
The soils can act as a source or carbon sink to the atmosphere, depending on the climate conditions and, especially, the type of use and management adopted. Taking into consideration the stock/sequestration carbon potential, admittedly, attributed to several land uses, as in planted forests (Pinus and Eucaliptus), and no-till areas, as well as the efficiency

9. Analysis of landslides susceptibility and use and landcover evolution of Paraty City - RJ / Análise da suscetibilidade a escorregamentos e as implicações da evolução do uso e cobertura do solo no município de Paraty, RJ
The city of Paraty is located between the Angra dos Reis and Ubatuba municipalities, stages of a numerous episodes of landslides. As the neighboring cities is marked by the presence of the Serra do Mar, where the shallow landslides in the form of translational movements account for most of the evolution of relief. And yet, there is no reference to deaths ass

10. Effects of habitat and landscape characteristics on medium and large mammal species richness and composition in northern Uruguay
The increasing world population and demand for food and other products has accelerated the conversion of natural habitats into agricultural lands, plantations and urban areas. Changes in habitat and landscape characteristics due to land-use change can have a significant effect on species presence, abundance, and distribution. Multi-scale approaches have been

11. Classificação da cobertura da terra e do uso do solo urbano utilizando o sistema InterIMAGE e imagens do sensor QuickBird / Urban land cover and land use classification using the InterIMAGE system and QuickBird imagery
The object-based image analysis approach is presently the state of art for the classification of high spatial resolution imagery, specially in urban areas. Nevertheless, the cost of licenses of commercial software packages for these tasks is very high. InterIMAGE is an open source knowledge-based classification system whose image analysis concept is highly f

12. Aspectos geoambientais e epidemiológicos em áreas de transmissão da hantavirose no Distrito Federal : estudo de caso - São Sebastião 2004 a 2008
The Hantaviruses have worldwide distribution and are important public health problem. The epidemiology of Hantaviruses in Brazil shows that is increasing every year the number of cases that are reported and variants have been discovered in several states and the Federal District. In this context, the study has as main objective to examine the influence of cl
