چکیده

O mapeamento do uso/cobertura da terra desempenha um papel vital no planejamento e supervisão utilização dos recursos naturais com base aumento gradual das demandas humanas ecossistema atual. As detecções de mudanças na cobertura solo são essenciais para entender quais vetores degradação atuam região, além monitoramento risco ambiental entorno reservatórios abastecimento água Bioma Caatinga. sensoriamento remoto o classificador SVM fornecem uma plataforma consistente estudar as transformações paisagem em toda a superfície Terra. Este estudo objetiva uso ocupação Barragem barra Juá localizado estado Pernambuco através comparação entre sensores orbitais, Câmera Multiespectral Regular (MUX) Operational Land Instrument (OLI) satélites CBERS-4 Landsat-8 respectivamente. A análises foram baseadas Tabela Contingência obtidas por meio mapa oficial referência. Após verificações comparativas produto referência, obtidos acurácia produtor usuário médio 62,44% 71,74% MUX 60,88% 62,38% OLI, diferentes especificações capacidades técnicas os captura bem como comportamento espectral alvos relevantes variabilidade espacial temática mapas OLI. Os resultados mostraram que apresentou melhor desempenho relação aos dados Support Vector Machines classifier for land cover mapping using CBERS-4/MUX and Landsat-8/OLI images B S T R C TLand use/land plays role in planning supervising the use of natural resources based on increase human demands today's ecosystem.

Análise da Complexidade de Texturas em Imagens Urbanas Utilizando Dimensão Fractal

This paper presents a study of the correlation between Fractal Dimension and urban morphological patterns. In remote sensing images, the urban morphological patterns are represented by complex interations of different surfaces, and each surface corresponds to a kind of texture. In this work, Fractal Dimension measures are applied to estimate the texture in remote sensing images from some urban ...

Aplicação de Modelos de Aprendizado Semissupervisionado na Classificação de Imagens de Sensoriamento Remoto

In many applications, the dearth of information to a proper training and use of supervised Machine Learning methods is a persistent problem. This fact led to the development of the semi-supervised learning paradigm. This paradigm can be understood as a combination of concepts of unsupervised and supervised paradigms. The way how the learning is conducted allows to organize the semi-supervised m...

Dinamica fluvial do rio Amazonas entre Manaus e Itacoatiara com o uso de imagens de satelite

The Amazon river is subject to major geomorphological changes between the hydrologic periods of flood and dry. Such changes can be mapped and detected by remote sensing techniques. In this context, this research had as objective to evaluate the dynamics of this great fluvial system, in the stretch between the cities of Manaus and Itacoatiara, in the period of 20 years. The results showed the pr...
