Quick assessment on identification of damaged building and land‐use changes in the post‐tsunami disaster with a quick‐look image of IKONOS and Quickbird (a case study in Meulaboh City, Aceh)
The study shows how far remote-sensing technology can contribute to assess quickly the impact of the tsunami disaster in Aceh, Indonesia. It focuses on the identification of damaged buildings and land-use changes in the post-tsunami disaster using a quick-look image of IKONOS and Quickbird. The method includes pre-processing, on-screen digitizing, change detection, and generating thematic maps. The results obtained from the study include information about distribution of damaged buildings, land-use changes, and total coverage of land affected by the tsunami disaster. Building units decreased almost 85%, from 4546 units to 649 units. Up to 2 303 046m2 of vegetated became mud-covered, while there was a decrease in the area of vegetated land, up to 1 869 676m2. For the relocation stage, the proposed method, called a quick standard procedure, is an appropriate approach which needs to be adopted by local government, nongovernmental organizations, and volunteers.
