<div style='text-align:Left;'><div><div><p><span style='font-weight:bold;'>Background: </span></p><p><span>MODIS Flood 1 Day Observations is a collection of GeoTiffs representing 1D1OS WMP : 1 Day imagery, 1 Observations required, Terrain & Cloud Shadow Masking. NASA Goddard's Hydrology Laboratory is working to operationalize near real-time global flood mapping using available satellite data resources -- currently the twice daily overpass of the MODIS instrument, on the Terra and Aqua satellites. We are working to include additional data sources, such as Landsat and radar, to improve coverage and accuracy. This work builds on the long-time expertise and efforts of the Dartmouth Flood Observatory (DFO) to map floodwater extent in detail for active floods. The DFO website provides additional detail, additional products, and archives of historical flood maps. This NASA website provides links and information about the automated daily flood and surface water products produced at NASA Goddard. </span></p><p><span style='font-weight:bold;'>Data Visualization: </span></p><p><span>MODIS Flood layer is represented using Unique Values Ranging from 0-3. </span></p><ul><li><p><span>0 : Insufficient data to make water determination (cloudy, missing images, swath gaps, or bad data values). </span></p></li><li><p><span>1 : No water detected. </span></p></li><li><p><span>2 : Water detected AND coinciding with reference water (e.g., not flood). </span></p></li><li><p><span>3 : Water detected, beyond reference water, so may be flood. </span></p></li></ul><p><span style='font-weight:bold;'>Daily Suggested Usage: </span></p><p><span>Flood detection and showing areas of surface water inundation.
