Digital change detection is the computerized process of identifying changes in the state of an object, or other earth-surface features, between different dates. During the last years, a large number of change detection methods have evolved that differ widely in refinement, robustness and complexity. This study aims to develop a program to detect and delineate landscape changes automatically over multiple...
A consistent data acquisition interval among multi-temporal images is necessary to accurate landscape change detection and temporal-series signatures. Orbital images are difficult to maintain a temporal precision due to the different interferences that generate missing data. The correct handling of missing data is a difficult problem in data analysis and often depends on your specific situation. This...
Natural disasters are one of the world's greatest socioeconomic problems and one of the most notable of which is that of mass movements, which are natural phenomena that change the relief and cause great damage to mankind. Mass movements can be classified by: type of material involved, velocity and mechanism of movement, type of deformation, geometry of the displaced mass and water content. Among...
The present work aims to evaluate the advantages of the ASTER sensor to detect Brazilian Savanna vegetation types over ultramafic or mafic rocks from spectral mixture analysis. The study area, the Niquelandia Complex, lies in the central portion of the State of Goias in Brazil. The Niquelandia Complex is a well-exposed heavily layered intrusion in central Brazil that comprises an area of about 1,800...
