Abstract:
Global Flood Hazard Frequency and Distribution is a 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. This dataset is the result of collaboration among the Columbia University Center for Hazards and Risk Research (CHRR) and Columbia University Center for International Earth Science Information Network (CIESIN). The data in American Standard Code for Information Interchange (ASCII) format and a map in Portable Document Format (PDF) and Portable Network Graphics (PNG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC). To provide a means of assessing the relative distribution and frequency of global flood hazard.

Attribute_Accuracy_Report:
The data from the Dartmouth Flood Observatory contains various geospatial representations of flood events. Some floods are depicted as points georeferenced to the nearest degree. Other floods are characterized by polygons. To determine frequency of flood hazard, a 2.5 minute grid overlays the flood data and the number of flood events per grid cell is recorded. A flood event is defined as any portion of any type of flood representation occurring within a grid cell. Therefore, if a grid cell is crossed by a boundary of a flood polygon, then the frequency increases by one. If a point is within the grid cell boundaries, the frequency increases by one. Flooding of the same areas, but at different times, also increase the frequency. The frequency range is classified into deciles, 10 classes of an approximately equal number of grid cells. Deciles are the chosen method of dissemination due to considerations of confidence with the data. Note that areas of &No Data& are not necessarily without risk of hazard, but may be artifacts of a mask that excluded from analysis those areas that were of a population density less than 5 persons per square kilometer and without significant agriculture.
