MODIS Flood Maps

Data Access

Floods are determined by use of daily MODIS 250 meter data, processed via decision tree algorithm to determine presence of water. The resultant map is compared to a static water mask to identify deviations, which are then labeled as flood. The method is limited by the sensor which is limited to visible observations, hence clouds obscure the view. An example of this process is the 2008 US Midwest floods, occurring due to unusually heavy rains in the northern Midwest causing flooding all down the Mississippi basin.
