Abstract: Medium (25 meter) resolution satellite radar imagery was used to identify damage from the SE Asia tsunami of December 2004. Several analysis methods were used on test areas over the Andaman and Nicobar Islands and NW Sumatra: visual assessment of before-after colour composites, pixel-based CFAR ratio change detection, and object-based classification and change detection. For validation, results were compared with optical high-resolution imagery and local reports. It is concluded that medium resolution radar imagery can detect coastal damage, coastline changes, inundation and areas of razed vegetation. It cannot reliably detect damage to built-up areas, roads and bridges.
