Large Scale Flood Hazard Maps

The Dartmouth Flood Observatory (Department of Geography, Dartmouth College, Hanover, NH 03755 USA) can now provide high quality, large scale flood hazard maps in digital (.pdf) and paper format. Coverage is global.

The maps extend 1degree latitude x 2 degrees longitude, and are in local UTM zone projections, at 1:250,000 scale, WGS 84 datum. There is a superimposed 10 km gray line graticule. Custom designed maps are also available at different scales or in different projections, as per request.

Our maps commonly include a color shaded relief base that is derived from the NASA SRTM topographic data (90 m posting interval). They include standard hydrography (normal surface water) as imaged by MODIS.

Flood hazard is depicted as in the on-line global series (see Atlas of Global Flood Hazard, at this web site). The areas subject to flooding are based on, at least, 5 years of satellite remote sensing, up to and including flood events in 2004.

Data sources are primarily the MODIS sensors aboard the Terra and Aqua satellites. Other satellites are used locally, including Landsat and Radarsat. The maps illustrate in much greater detail what is provided online at a reduced scale in reduced resolution, jpeg format at the Flood Observatory web site.

Contact Brakenridge@Dartmouth.edu or Elaine.Anderson@Dartmouth.edu for more information or to order. Please specify area of interest and including the total geographic coverage needed.
