| KRATKA VSEBINA | In SAR images, the pixel values are tightly related to physical parameters of the soil such as topography, roughness and humidity, regardless to atmosphericconditions. Therefore, SAR images may be used to detect, and quantify changes in land cover, by comparison oftime series SAR data. Classical change detection techniques from SAR imagesare based on additive synthesis of RGB colors and arithmetic operations between images. The noisy aspect of ERS image due to the original speckle is an obstacle for available mapping and quantification of the changes. Here, statistical and morphologicalfilters are used to reduce the speckle noise. Combined techniquesof change detection and noise filtering are applied here to assess and map from ERS-SAR images the impact of regular orcatastrophic flood and deforestation in the East Coast of Madagascar. |
