WebThis approach produces a Landsat-scale image for fine-scale flood mapping of areas where there are no observed cloud-free Landsat or similar resolution satellite images. The fusion model was implemented on atmospherically corrected surface reflectance, and the resultant reflectance values were validated by comparing with observed Landsat … WebThe results show that the northern districts viz. Darbhanga and Narayanpur and the eastern district viz. Katihar and Purnea were the worst affected. The obtained results were verified using news agencies, state disaster management board maps, and inundation map of MODIS Flood map products.

Web27 jun. 2014 · The MODIS sensors (TERRA and AQUA) can be used for mapping flood events due to their near-global spatial (250–1000 m) and temporal characteristics (1–2 times/day). Furthermore, all historical data from 2000 to present are readily available. MODIS bands 1 (Red) and 2 (NIR) are at 250 m pixel size which can be used to map … WebCSIRO Research Publications Repository - MODIS-based standing water detection for flood and large reservoir mapping: Algorithm development and applications for the Australian continent MODIS-based standing water detection for flood and large reservoir mapping: Algorithm development and applications for the Australian continent … gaming computers pay monthly
