Comparação de Imagens OLI/Landsat-8 e MSI/Sentinel-2 no mapeamento de cobertura...
Freires, Eduardo Viana; Silva Neto, Cláudio Ângelo da; Cunha, Dominick Sávio Rocha; Duarte, Cynthia Romariz; Veríssimo, César Ulisses VieiraOrbital images of the Landsat series have been systematically employed in the mapping of land cover and use. However, some areas, due to the relief characteristics or the strong antropic influence, impose difficulties in this characterization. The Uruburetama massif, in the state of Ceará, represents an area with such peculiarities. This work compares images of the OLI / Landsat-8 and MSI / Sentinel-2 orbital s...
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...
Caracterização dos setores erosivos e deposicionais da linha de costa de Icapuí...
Silva Neto, Cláudio Ângelo da; Duarte, Cynthia Romariz; Souto, Michael Vandesteen Silva; Freire, Eduardo Viana; Sousa, Willamys Rangel Nunes deThe importance of coastal zones implies the need for continuous studies related to the monitoring of their processes. In this context, the shoreline represents one of the most dynamic features, and its variability is an indicator of erosion or coastal deposition. In order to evaluate the changing trends of the coast of the Icapuí city, located in the far east of the state of Ceará, this work involved the use of...
Variação da linha de costa no litoral cearense (1984-2018)
Silva, Maykon Targino da; Lopes, Débora Nogueira; Rebouças, Iago Silva; Freires, Eduardo Viana; Silva Neto, Cláudio Ângelo da; Duarte, Cynthia RomarizCoastal erosion occurs in several parts of the world. Sometimes, it destroys structures close to the shoreline causing economic damage. In the state of Ceará, Brazil, there are stretches with retrogradation. A classic example is from the area near the Mucuripe harbor (Fortaleza). From this context, the objective of this paper was to analyze the evolution of the State of Ceará shoreline between 1984 and 2018. To...
Aproveitamento dos rejeitos das indústrias de calcinação de calcário na porção ...
Pessoa, Antônia de Castro Côrtes; Machado, Francisco Pessoa; Silva Neto, Cláudio Ângelo da; Sabadia, José Antonio Beltrão; Duarte, Cynthia RomarizThe residues generated in the limestone calcination process form piles sources of degradation of the environment and obstacles to the good progress of the activities of the producing units. The use of these tailings might generate benefits to the environment, as well as improvements to the job of the workers, besides being another source of income for the local calcination industries. This study was developed i...
Influência de lineamentos estruturais no desencadeamento dos movimentos de mass...
Freires, Eduardo Viana; Silva Neto, Cláudio Ângelo da; Duarte, Cynthia Romariz; Veríssimo, César Ulisses Vieira; Gomes, Daniel Dantas MoreiraThe geological structures arrangement in plateau areas is an important element in understanding the dynamics that occur on the surface of their slopes and which is responsible for relief sculpting. In this context, gravitational movements stand out, which can generate economic, environmental and human losses in high energy events and / or with large extension. This research analyzed the influence of structural ...
Diagnóstico da degradação ambiental na vertente úmida do Maciço de Uruburetama/...
Freires, Eduardo Viana; Silva Neto, Cláudio Ângelo da; Duarte, Cynthia Romariz; Veríssimo, César Ulisses Vieira; Gomes, Daniel Dantas MoreiraThe various interventions in the Uruburetama Massif have generated a situation of degradation that compromises local economic, social and environmental sustainability. As a way of warning about the worsening of environmental problems, this research aims to make a diagnosis of environmental degradation in the humid hillside of the Uruburetama Massif / CE and its surroundings, in order to assess the impacts gener...
Um novo método de avaliação da correspondência entre lineamentos de superfície ...
Silva Neto, Cláudio Ângelo daStudies that assess the correspondence between deep structures and their possible expression on the surface visually compare magnetic and relief linear features, overlapping them on thematic maps or evaluating the spatial variability of each one separatelyusing density maps. This work proposes a new method for assessing lineaments, focusingon the quantitative and qualitative expressionof linear features regardi...
Caracterização geoecológica da zona costeira submersa a partir da cartografia s...
Moretz-Sohn, Clarissa Dantas; Barbosa, Larissa Neris; Melo, David Basílio de; Silva Neto, Cláudio Ângelo da; Santos, Inês Ribeiro dosA intensa dinâmica dos sistemas costeiros, oriunda da interação marinha e continental, forma um amplo conjunto de ecossistemas diferenciados que via ciclos de deposição e erosão dão origem a feições particulares das planícies costeiras. Entretanto, os ambientes litorâneos estão sujeitos a diversos tipos de impactos e conflitos. Assim, o planejamento participativo, onde o conhecimento tradicional é uma important...
