Land surface change detection in a desert area in Algeria using multi-temporal ERS SAR coherence images
Multi-temporal synthetic aperture radar (SAR) interferometric coherence imagery is a useful information source for the detection of random changes of the land surface. Three coherence images derived from three ERS-1 SAR images (acquired on 8 September 1992, 13 October 1992 and 28 September 1993) of a desert area in Algeria revealed several interesting phenomena, including distribution of mobile sand, erosion along river channels, variation of ephemeral lakes and 'mystery' seismic survey lines.
