The 2012_DFO_floodextent_v2 dataset is reflecting the accumulation of the daily MODIS Surface Water detection product “2D2O” of 2012 that is provided by the NASA’s MODIS Near Real-Time Global Flood Mapping Project, implementing the water detection algorithm of Dartmouth Flood Observatory (DFO). The applied daily 2D2O product is a moving 2 day composite of 4 MODIS images (2 by Terra and 2 by Aqua satellite). Water will be only be marked as surface water when: 1) for this moving 2day composite, 2 or more images indicate water at a certain location; 2) for two adjacent 2day composite files (reflecting two adjacent days) only the intersecting surface water cells that consist of 3 or more adjacent grid cells (each 250m2 large). The 2D2O product includes a first order approach by NASA to filter out terrain shadows, this is further enhanced by applying above mentioned filter. However, accumulating daily output over a year still tends to reflect incorrect surface water extents for mountainous regions. The 2012_DFO_floodextent_v2, version 2 dataset is a shapefile composite reflecting flood water extents for 2012 for South and Middle America.
