13. 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

15. 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

16. A influência do sistema Faxinal no Estado Ambiental da Bacia Hidrográfica do Rio Sete Saltos - PR
The Hydrographical Basin provides among its many potential natural features, such as, being a unit of management natural resource for easy definition. However, to diagnose the interaction between the physical and biotic aspects it is necessary to use techniques that allow this task. In this research it was used the Physical-Conservationist Diagnostic methodo

17. Uso de imagens MODIS no mapeamento de bacias hidrogrÃficas
This research focuses on display applications of MODIS (Moderate Resolution Spectroradiometer) and the different types of its products. The MODIS was design for analysis of changes on a global scale, thus having different environmental applications. This sensor has 36 bands and 44 products for different types of searches. The spatial resolution of MODIS imag

19. Land cover mapping of the metropolitan railway right of way: Line F in São Paulo. / Mapeamento da cobertura do solo ao longo da faixa de domínio de trem metropolitano: Linha F em São Paulo.
O transporte ferroviário de passageiros ganha importância estratégica na melhoria do trânsito e qualidade de vida dos grandes centros urbanos, mas no Brasil enfrenta sérios problemas operacionais, como obsolescência da infra-estrutura e invasão da faixa de domínio, comprometendo sua segurança e operacionalidade. O objetivo central deste trabalho é

20. Análise metodológica do tratamento de dados sar r99b para discriminar incremento de desflorestamento no sudoeste da amazônia brasileira
- The estimate and mapping of deforestation in Brazilian Amazon has been carried out yarly, with the objective to monitor the forest resources, and as a mean for giving support to governmental control actions. This systematic monitoring is executed by the PRODES Digital project, developed by the Brazilian National Institute for Space Research (INPE), using L

21. Mapeamento das estimativas do saldo de radiação e índices de vegetação em área do estado de Alagoas com base em sensores remotos. / Mapping of the estimates of the balance of radiation and indices of vegetation in an area of the state of Alagoas based on remote sensing.
The balance of radiation at the surface is of great importance in studies related to the flow of heat in the atmosphere, particularly in agricultural crops in areas and basins. This work mapped the components of the radiation balance of the land surface and vegetation indices of the area with the river basin Pratagy in Alagoas, by means of remote sensing dat

22. Avaliação sócio-ambiental do uso de efluente de esgoto tratado na irrigação de culturas no Município de Lins - SP / Socioenvironmental assessment of the use of treated sewage effluent in the irrigation of crops in Lins - SP
Worldwide, there is an increasing competition for the use of water between different sectors of society. The agriculture is a major consumer of the total fresh water available. In this context, it is desirable a reallocation of water resources used in agriculture to other sectors, such as public supply. Since done in a controlled way, irrigation with effluen

23. Evaluation of digital terrain model extracted from SAR data in X-Band of SAR R-99B / Avaliação do Modelo Digital do Terreno Extraído de Dados SAR Interferométricos na Banda X do SAR R-99B
In the Brazilian territory there are several areas with no topographic mapping coverage and the existent maps are not updated due to the continuous land use and land cover changes. The Sistema de Prote¸cao da Amazonia (SIPAM) uses airplanes with synthetic aperture radar which allows to image in several conditions. This radar was designed for recoinassance t
