1. Classificação de fragmentos florestais urbanos com base em métricas da paisagem
Resumo A urbanização no município de Campinas-SP e região ocorreu de forma rápida e intensa, provocando acentuadas alterações na paisagem e resultando em uma expressiva degradação das áreas florestais e da cobertura vegetal natural. Este fenômeno deu origem a um processo de fragmentação florestal bastante intenso. Neste contexto, mapear estes fr

2. 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

3. Methodology for classification of land use and vegetation cover using MODIS-EVI data
RESUMO Objetivou-se neste estudo verificar a aplicabilidade do uso de séries temporais do sensor MODIS-EVI para o mapeamento do uso do solo e cobertura vegetal no Bioma Pampa no Estado do Rio Grande do Sul. O período de estudo compreendeu os meses de junho de 2013 até junho de 2014. Os procedimentos incluíram a utilização de imagens do Sensor MODIS, da

4. Landscape Ecology in a Watershed of the Ocoy River, Western Parana State, Brazil
ABSTRACT This study evaluated the landscape structure of a watershed located in a region considered strategic for the implementation of the Paraná River Biodiversity Corridor. Based on land-use/land-cover mapping, four different scenarios were generated: 1) real situation, 2) considering the edge effect, 3) without Permanent Preservation Areas (APPs), and

5. COMPARATIVE ASSESSMENT BETWEEN PER-PIXEL AND OBJECT-ORIENTED FOR MAPPING LAND COVER AND USE
ABSTRACT: The traditional per-pixel classification methods consider only spectral information, and may be limited. Object-based classifiers, however, also consider shape and texture, firstly segmenting the image, and then classifying individual objects. Thus, a Geographic Object-Based Image Analysis (GEOBIA) was compared in conjunction with data mining techn

6. The role of terrestrial bromeliads in determining the spatial organization of plant life forms in a tropical coastal forest
ABSTRACT The interplay between plant-plant interactions and light heterogeneity in the understory of tropical forests has rarely been examined. We aimed to identify the relative importance of the understory light environment and terrestrial bromeliads in explaining the abundance and spatial organization of different plant life forms along a coastal forest gr

7. Anopheles fauna of coastal Cayenne, French Guiana: modelling and mapping of species presence using remotely sensed land cover data
Little is known about the Anopheles species of the coastal areas of French Guiana, or their spatiotemporal distribution or environmental determinants. The present study aimed to (1) document the distribution of Anopheles fauna in the coastal area around Cayenne, and (2) investigate the use of remotely sensed land cover data as proxies of Anopheles presence.

8. Landscape and soil regionalization in southern Brazilian Amazon and contiguous areas: methodology and relevance for ecological studies
Soils of a large tropical area with differentiated landscapes cannot be treated uniformly for ecological applications. We intend to develop a framework based on physiography that can be used in regional applications. The study region occupies more than 1.1 million km² and is located at the junction of the savanna region of Central Brazil and the Amazon fore

9. Análise de imagem polarimétrica TerraSAR-X para classificação de uso e cobertura da terra na porção sudoeste da Amazônia Brasileira / TerraSAR-X image for classification the land use and land cover in the southwest portion of the Brazilian Amazon
The objective of this study is to analyze the potential use of images from satellite TerraSAR-X, at StripMap acquisition mode, to map and identify the land use and land cover (LULC) in the southwestern Brazilian Amazon. Classifiers based on statistical functions for maximum likelihood (ML) method and based on frequency-based contextual and neural network cla

10. Alteração no uso e cobertura do solo na bacia do médio rio Araguaia, Brasil central / Land use land and cover changes in the middle Araguaia river basin, central Brazil
The central region of the Araguaia river basin encompasses a transition area between the Tropical Rain Forest and the Cerrado in Brazil. Despite of the fact that during the last four decades, this area has undergone an intense deforestation process, the quantification and impact of these changes are still unknown. Thus this study aimed to evaluate the dynami

11. Mapping of permanent preservation areas de and land use conflict in rural properties / Mapeamento de áreas de preservação permanente e dos conflitos de uso da terra em propriedades rurais
This work had the following objectives: to elaborate a map of basin land use by properties based on Ikonos II ortho image; to automatically delimit the permanent preservation areas; to evaluate the dynamics of the fragmentation process; and to identify the occurrence of land use conflict by properties on the São Bartolomeu stream basin, located at the Zona

12. Orthoretification of high-resolution images for application in rural technical cadastral and mapping of permanent preservation and legal reserve areas / Ortorretificação de imagens de alta resolução para aplicação em cadastro técnico rural e mapeamento de áreas de preservação permanente e reservas legais
Besides the vast interpretative information generated after being submitted to geometric corrections, high spatial resolution orbital images allow extracting geometric information (angles, distances and areas). Different correction methods can be used for this purpose. If the method used corrects relief influence, it carries out image orthoretification, and
