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...
Caracterização espectrorradiométrica do minério magnesítico da porção Centro-Su...
Souza, Cassiano Dias deThis work has as objective the spectroradiometric characterization of magnesitic ore of the south-central portion of the state of Ceará through reflectance spectroradiometry. The samples collected from the mines of Torto, Riacho Fundo and Cabeça de Negro, located between the municipalities of Orós and Jucás, were cut ad polished, in order to obtain uniform surfaces, and to minimize the effect of the relief and ...

Souza, Cassiano Dias de; Silva, Rayssa Magdyelli Nogueira da; Rodrigues, Linara Ivina de Castro; Mororó, Emanuel Andrade AlbuquerqueThe Coastal areas of Ceará are on constant modification, both due to the action of Coastal dynamics and anthropogenic actions. The objective of this work was the analysis on the evolution of the coastline between the years 1984 and 2013 using digital image Processing techniques in images of satellites Landsat 5 (TM) and Landsat 8 (OLI). The study area is located between the Praia do Preá and the Rio Aracati-Mir...
