Análise comparativa de imagens Sentinel-2A (MSI) e Landsat-8 (OLI) aplicadas ao...
Miranda, Mateus de Paula; Duarte, Cynthia Romariz; Gomes, Daniel Dantas Moreira; Souza, Cassiano Dias de; Silva Neto, Cláudio Ângelo daSatellites equipped with multispectral sensors, such as the Landsat (TM, ETM +, OLI) series, play an important role in geological applications, especially sensors that have spectral bands in short-wave infrared, because it is in this region of the spectrum that mineral groups such as that of the clays, present peaks of reflectance. The satellite of the mission Sentinel-2, from Copernicus program of European Spa...
Imagens Sentinel-2 aplicadas na caracterização geomorfológica de ambientes cost...
Silva Neto, Cláudio Ângelo da; Maia, Allison de Oliveira; Miranda, Mateus de Paula; Duarte, Cynthia Romariz; Souto, Michael Vandesteen SilvaCoastal regions are dynamic environments formed from the joint action of wind, terrestrial, oceanic & atmospheric processes. Remote sensing, coupled with digital image processing & geographic information systems, has been used in studies related to the coastal environments. The use of these geotechnologies finds it difficult to individualize geomorphological compartments of the coast due to the compositional ho...

Miranda, Mateus de Paula; Pontes, Marcos Paulo; Morais, Pedro Ângelo Silva de; Uchoa, Elenilton Bezerra; Duarte, Cynthia RomarizThis study aimed in the use of digital Processing techniques of remote sensing images, color composite RGB, bands subtraction and Principal Component Analysis - PCA (Crosta Technique) in scenes of OLI sensor, satellite Landsat 8, to assist in geological mapping, lithology identification and structure enhancement. The study area is located in the town of Canindé, inserted in Ceará Central Domain (neoarchans rock...
Imagens sentinel-2a (msi) aplicadas ao mapeamento geológico, Região de Itataia,...
Miranda, Mateus de PaulaThe phosphorus-uraniferous province of the Itataia region, object of this study, is located in the municipality of Santa Quitéria / CE and inserted in the geological context of Ceará Central Domain (DCC) of the Borborema Province (PB). It is a unique mineralization in the world where Its main ore is colofanite. Satellites equipped with multispectral sensors such as Landsat (TM, ETM +, OLI) series play an import...
Emprego de sensoriamento remoto e gamaespectrometria na avaliação da mineraliza...
Miranda, Mateus de PaulaThis project aimed to characterize the phosphorus-uranium of Itatiaia mineralization using gamma ray spectrometric data and optical remote sensing images. The phosphorus-uranium province is located in the municipality of Santa Quitéria-CE, central of the Ceará state, included in the Central Ceará Domain. The ore deposit is colophanite that occurs in different forms and is primarily associated with silicate and ...
