World Atlas of Flooded Lands: E20N20

To create this Atlas, satellite data are obtained by the Flood Observatory, processed to detect water/land boundaries, geocoded to standard UTM map projections, and analyzed to produce inundation limits in vector GIS format. The maps are continually updated from archival satellite data and also when new floods occur. The Atlas is thereby a work in-progress and is becoming increasingly comprehensive as new events are added. Original GIS vector data (inundation limits only) are also available as MapInfo export format files and can be used to study in more detail inundation during each year, or that resulting from a particular flood.

Map Number gives geographic coordinates of upper left corner of map. Most maps measure 10 degrees in both longtitude and latitude.

Caution to all users: Floods in mountainous regions are exceptionally hazardous, but they are difficult remote sensing targets and not always observable. Additionally, cloud cover or other constraints sometimes restrict the ability to capture peak inundation. The maps in this Atlas do not illustrate all areas of possible flood hazard.
