[HDS07-P04] Quantifying damages brought by tropical typhoons using remote sensing
Keywords:remote sensing, typhoons, damage assessment
Remote sensing has been widely used in assessing damages from disasters. Compared with field survey, it is a cost effective tool. In this study we compared pre- and post-typhoon satellite images by calculating for different vegetation indices such as Normalized Vegetation Index (NDVI), Normalized Difference Infrared Index (NDII) and Enhanced Vegetation Index (EVI). We found that the largest change is calculated using NDII. We analyzed satellite images from Landsat 8 for tropical storms that passed by the Philippines and Japan. We also correlated the rainfall volume measured by rain gauges to the damages measured by the satellite images.
