Abstract :
The authors developed a method of object-based satellite image analysis using high-resolution post-tsunami satellite image to detect and map tsunami impact. The method is applied to QuickBird 4 band pan-sharpened composite image acquired in Banda Aceh, Indonesia, and the ground objects are classified into six ; vegetation, water, soil, building, road and debris, for mapping the impact of the 2004 Sumatra Andaman earthquake tsunami.
