New: DFO's ESA/Copernicus Sentinel 1-based mapping of flooding in Central USA, February 26, 2018. Mapping in progress; map results posted here when available. See also the DFO Map Server with both the Sentinel 1 information and MODIS data from the automated processor.. Below is the gauging station information from USGS/NOAA and some sample Sentinel 1-based change detection images (flooding in red, February 25, 2018).
Flooding in NE India, July 15, 2017. Red shows current surface water; blue is typical winter conditions; light gray is all previously mapped flooding. Click on dots to retrieve microwave observation of changing river discharge. See also: 090E030N
