| ABSTRACT Although soybean production has been increasing in the state of Rondônia in the last decade, soybean planted area has been estimated indirectly using secondary datasets, which has limited understanding of its spatiotemporal distribution patterns. This study aimed to map and analyze spatial patterns of soybean expansion in Rondônia. We developed a classification technique based on Spectral Mixture Analysis (SMA) derived from Landsat imagery and Decision Tree Classification to detect and map soybean plantations in 2000, 2005, 2010, and 2014. The soybean classification map showed 93% global accuracy, 23% omission and 0% of commission errors for soybean crop fields. The greatest increases of soybean cropped area in the state of Rondônia were observed... |

| Neste trabalho, com base em Geoprocessamento e pesquisas de campo, o objetivo é identificar áreas susceptíveis à erosão na cabeceira da bacia do rio Atibaia, ou seja, as bacias dos rios Cachoeira e Atibainha a montante das barragens do Sistema Cantareira. Em relação ao relevo, além das características de declive, as áreas saturadas de água também interferem no escoamento superficial das vertentes, sendo consideradas, portanto, áreas susceptíveis à erosão. Cruzaram-se informações de relevo (declividades e áreas saturadas), uso e ocupação das terras e seus respectivos procedimentos em dois cenários: os dos anos de 1986 e 2005. Os resultados indicaram que, em 1986 e 2005, o uso e ocupação são mata nativa, pastagem e silvicultura e que está ocorrendo uma... |

| ABSTRACT The World Health Organization (WHO) estimates that approximately 2 billion people worldwide have already had contact with hepatitis B virus (HBV) and 373 million have become chronic carriers. Hepatitis B is a major cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma, leading to a large number of deaths annually. Both viral factors and the host immune response have been implicated in the pathogenesis and clinical result of HBV infection. Many Brazilian cities, including the cities of the northern region of the state of Espírito Santo are located in regions with little health infrastructure. Our study performed an epidemiological analysis of cases of Hepatitis B in São Mateus, using methodology of Geographic Information System (GIS),... |

| The Permanent Preservation Areas (PPAs) are considered essential for the maintenance of local biodiversity, so that your protection is regulated by the Brazilian legislation. This work had the objective of delimiting permanent preservation areas according to determinations of the current Brazilian environmental legislation, and identify the occurrence of conflict between the land use and legislation in Lavras county, MG, by combination of technologies of remote sensing and geographic information systems. The PPAs correspond to 42.33% of Lavras county's territory. The conflict between the land use and environmental legislation occurs in 63.48% of PPAs' territory, mainly corresponding to the pasture areas, bare soil and agriculture. The PPAs of tops of hills... |

| Lands (broader concept than soils, including all elements of the environment: soils, geology, topography, climate, water resources, flora and fauna, and the effects of anthropogenic activities) of the state of Minas Gerais are in different soil, climate and socio-economics conditions and suitability for the production of agricultural goods is therefore distinct and mapping of agricultural suitability of the state lands is crucial for planning guided sustainability. Geoprocessing uses geographic information treatment techniques and GIS allows to evaluate geographic phenomena and their interrelationships using digital maps. To evaluate the agricultural suitability of state lands, we used soil maps, field knowledge, forest inventories and databases related to... |

| The use of geoprocessing has become a more important tool to map areas with substance concentrations above the patterns that may affect the quality of the water. The objective of such study was to evaluate the quality of the superficial waters of the rivers in Rondônia used for to the supplying. Through the espace measurement of the color and turbidity isoconcentration it was inferred that the quality of the waters are in agreement with the maximum limits allowed by the resolution of CONAMA n. 357/05. |

| The present study aimed to use Geoprocessing techniques applied to basin management. The study area was the Guariroba microbasin in Campo Grande city - MS. Using the Digital Terrain Model, from EMBRAPA website, topographical data were extracted in Arcgis environment, a TIN grade was generated and from its, a hypsometric map and a three-dimensional declivity map. The land use/cover was also mapped, using a CBERS image and the MAXVER algorithm in ERDAS environment. The Guariroba basin presents low levels of declivity, with fragments of native vegetation and high degree of degradation, distributed in 24 % of the total of the area of the basin. |

| ABSTRACT This study demonstrates using remote sensing, geographic information systems and multivariate statistics to study water quality in an agricultural watershed. The monitoring of water quality in the watershed of Lontras's river in the southwestern region of the State of Paraná had been done in 2012 and 2013 with a multi-parameter probe in ten sites that were defined upstream and downstream watershed, during four different seasons. Mosaicked images were used from Google Earth, Digital Elevation Model and soil types of maps, defined as the explanatory variables. The definition of the areas of influence and multivariate statistical techniques, particularly the Redundancy Analysis (RDA), were used for the correlation between variables. In a spring area,... |

| In Brazil, the State of Goiás is one of sugarcane expansion's frontiers to meet the growing demand for biofuels. The objective of this study was to identify the municipalities where there were replacement of annual crops (mainly grains) by sugarcane in the state of Goiás, as well as indicate correlations between the sugarcane expansion and the family farming production, in the period between 2005 and 2010. For this purpose, grains crop mask and sugarcane crop mask, obtained from satellite images, were intersected using geoprocessing techniques. It was also used IBGE data of sugarcane production and planted area, and data of family farming production linked with the National Food Acquisition Program (PAA), in relation to the number of cooperatives and... |

| Visceral Leishmaniasis (VL) is caused by protozoan of genus Leishmania and transmitted by sand flies of genus Lutzomyia, which has been adapted to the peridomicile environment where dogs are their mainly food source, increasing the risk for human cases. In this study, techniques of geoprocessing and spatial statistics were utilized as a contribution to understanding the epidemiological dynamics of VL in the urban area of Ilha Solteira, SP. |
