Global Flood Hazard Frequency and Distribution is a 2.5 by 2.5 minute
grid derived from a global listing of extreme flood events between 1985
and 2003 (poor or missing data in the early/mid 1990s) compiled by
Dartmouth Flood Observatory and georeferenced to the nearest degree. The
resultant flood frequency grid was then classified into 10 classes of
approximately equal number of grid cells. The greater the grid cell
value in the final data set, the higher the relative frequency of flood
occurrence. The dataset is a result of the collaboration among the
Center for Hazards and Risk Research (CHRR) , and the Columbia
University Center for International Earth Science Information Network(CIESIN).
