1. Estimativa da Evapotranspiração e Fluxos de Energia de Superfície Usando a Imagem Landsat-7 Enhanced Thematic Mapper Plus em um Agrosistema Aemi-árido no Noroeste da Argélia
Resumo O monitoramento dos fluxos de energia e da evapotranspiração em diferentes escalas espaciais e temporais é crucial para muitas aplicações agroambientais. Diferentes modelos baseados no sensoriamento remoto têm sido desenvolvidos para estimativa da evapotranspiração tanto em escala local como em largas escalas. Neste contexto, o METRIC (Mapping

3. 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

4. Geotecnologias como contribuição ao estudo do agroecossistema cafeeiro de Minas Gerais em nível municipal / Geotechnologies as contribution to the study of coffee crop agro system at municipal level in Minas Gerais state
Coffee crop, an important economic and social activity to Brazil, is an agrobusiness segment that has not updated information about the agroecosystem and the productive profile. In this sense, it was proposed in the year of 2004 a multidisciplinary and multi institutional project, involving INPE, EMBRAPA and UFLA to characterize the coffee agroecosystem in M

6. Mapeamento de áreas susceptíveis a escorregamentos no município de Caraguatatuba (SP) usando técnicas de sensoriamento remoto e SIG / Landslide susceptibility mapping in Caraguatatuba (SP) municipality using remote sensing and gis techniques
The objective of the present research was the development of a quantitative approach for landslide susceptibility mapping using remote sensing and GIS techniques. In order to determine the best products for identifying landslide scars, six imagery fusion techniques (Brovey, HSV, PCA, IHS and two Wavelets) were evaluated and many geographical inference approa

10. Proposta conceitual de zoneamento ambiental para o Município de Erechim (RS). / Conceptual proposal of environmental zoning for the Municipality of Erechim (Rio Grande do Sul State).
This work proposed an environmental zoning based on the potencialities and fragilities of the use of the land. Its perspective was to subsidize the elaboration of proposals and lines of direction for the re-ordering of the landscape of the municipality of Erechim, contributing to local-regional development. The town is a part of the Geographic Micro-region o

11. Caracterização e mapeamento da vegetação da região da Floresta Nacional de Tapajós através de dados óticos, de radar e inventários florestais / Vegetation characterization and mapping of Tapajós national forest region through optico, radar and forest inventory data
The Tapajós National Forest (FNT) has been observed by several remote sensor types, for many years. As one of the main study sites of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) project, the FNT has been object of several remote sensing campaigns. However, the papers that have tried to integrate the information originating from the mul

12. Classificação e monitoramento fenológico foliar da cobertura vegetal na região da floresta Nacional do Tapajós - Pará, utilizando dados multitemporais do sensor "thematic mapper" (TM) do Landsat / Phenology foliar classification and monitoring the vegetation cover in the Tapajós National Forest region Pará State, utilization multitemporal data from Landsat Thematic Mapper (TM) sensor
The relative importance of accuracy in forest cover mapping is given by the necessity to obtain improvement in the elaboration of a management plan of natural resources and in the definition of priority areas for conservation, as well as in landscape analysis. Other aspect that has raised even more interest in the scientific community is concerned to modelin
