(Mathematics Of Planet Earth, 2014-01-01) [Trabalho apresentado em evento]
Caracterização magnetométrica do Sill de Limeira-SP
(Geociências, 2015) [Artigo]
The purpose of this study is to characterize the geological subsurface structure of the diabase sill of the Paraná Magmatic Province intruded in the Itararé Group, located near the city of Limeira, in the east-central ...
Magnetometric exploration in intrusive basic with evidence of gold in northern region of the Camaquã Sedimentary Basin (RS)
(REM. Revista Escola de Minas, 2015) [Artigo]
This study involved magnetometric exploration in the region of São Sepé (RS), southern Brazil, to evaluate the potential for gold mineralization in a gabbro using evidence previously obtained from the geochemical exploration ...
Estudo geofísico de vazamento controlado de álcool combustível em escala laboratorial
(Revista Brasileira de Geofísica, 2011-06-01) [Artigo]
O etanol é utilizado de forma extensiva como combustível para veículos automotores no Brasil, devido tanto a características como ao clima favorável ao cultivo de cana-de-açúcar em uma cadeia produtiva bastante desenvolvida ...
Remote sensing analysis of depositional landforms in alluvial settings: Method development and application to the Taquari megafan, Pantanal (Brazil)
(Geomorphology, 2012-08-01) [Artigo]
Traditional Shuttle Radar Topography Mission (SRTM) topographic datasets hold limited value in the geomorphic analysis of low-relief terrains. To address this shortcoming, this paper presents a series of techniques designed ...
Is it possible to make pixel-based radar image classification user-friendly?
(International Geoscience and Remote Sensing Symposium (IGARSS), 2011-11-16) [Trabalho apresentado em evento]
In this paper we would like to shed light the problem of efficiency and effectiveness of image classification in large datasets. As the amount of data to be processed and further classified has increased in the last years, ...
Automatic landslide recognition through Optimum-Path Forest
(International Geoscience and Remote Sensing Symposium (IGARSS), 2012-12-01) [Trabalho apresentado em evento]
In this paper we shed light over the problem of landslide automatic recognition using supervised classification, and we also introduced the OPF classifier in this context. We employed two images acquired from Geoeye-MS ...
O rio Paraguai no megaleque do Nabileque, sudoeste do Pantanal mato-grossense, MS
(Revista Brasileira de Geociencias, 2011-12-01) [Artigo]
The Nabileque fluvial fan is a Quaternary depositional system located along the southwestern border of the Pantanal, covering an area of approximately 9,100 km 2. It is a peculiar alluvial system because it is not associated ...
Paleocanais no megaleque do rio Taquari: mapeamento e signifcado geomorfológico
(Revista Brasileira de Geociencias, 2011-03-01) [Artigo]
This paper presents the results of the frst systematic mapping of the paleochannel network on the Taquari megafan (Pantanal, Brazil). We used remote sensing data collected by the ASTER sensor, which captures images with ...
Erosion rates and landscape evolution of the lowlands of the Upper Paraguay river basin (Brazil) from cosmogenic Be-10
(Geomorphology, 2015-04-01) [Artigo]
The importance of Earth's low sloping areas in regard to global erosion and sediment fluxes has been widely and vigorously debated. It is a crucial area of research to elucidate geologically meaningful rates of ...
