Fundamental of all plans of agriculture, forestry, range management and watershed management and aquifer and so on is physiographic study and determination of land talent. Cause of land use diversity in the region and soil erosion and degradation need to this study and be important. This study was conducted by satellite photos and topographical maps with 1:50000 scale. After load maps by GIS software,...
The difference synthetic aperture radar interferometer (D-InSAR) is developed based on the synthetic aperture radar (InSAR) technique. It can be used to detect the earth surface deformation, fire hazard, earthquake and etc.. The imaging principle and data process procedure are introduced. The difference interfere process of the SAR data from Bam in Iran where earthquake happened on Dec. 26th, 2003...
We focus on a geophysical application of image processing: the measurement of high resolution ground deformation from two optical satellite images taken at different dates. Disparity maps estimated from image pairs usually lack quantitative error estimates. This is a major issue for measuring physical parameters, such as ground deformation or topography variations. Thus, we propose a new method to...
A building damage assessment method applied to the case of the earthquake of Bam is proposed in this paper. It uses two very high resolution images and focuses on the footprints of the buildings. The need of an accurate registration of the buildings is demonstrated; a registration method that improved the damage assessment is proposed. It allows a classification performance of the buildings among...
