Monitoring and Assessment for the Tsunami Disaster of Indian Ocean by Remote Sensing: A Case Study in Aceh Province of Indonesia
印度洋海啸灾害遥感监测与评估——以印度尼西亚亚齐省为例

The Indian Ocean Tsunami disaster occurred on December 26 in 2004. This paper introduces the method and the result for monitoring and assessing this Tsunami disaster by the usage of new generation Moderate Resolution data from the British Disaster Monitoring Constellation(DMC). The multi-spectrum bands resolution is 32 meter. This work takes Aceh province of Indonesia as a case study. By pre-processing of DMC image, the analysis of the spectrum information for damaged ground objects, the contrast analysis of the interesting areas and their environment background information, the interpretation keys for each loss degree in grade has been established. Through interpreting DMC image, the boundary of all the damaged objects was elelineated according to the loss extent, then statistics and analysis were made for the tsunami disaster extent of disaster losses. Fast and macroscopic is its characteristic. The results of this paper show that the method is feasibly. It provides the objective and referenced information for the assistance of Chinese government. Moreover, it will provide the methodology for other disasters, and the application supports for the application of coming Disaster and Environment Forecast Constellation and Chinese DMC.
