When It Comes to Flood Mapping or Sea Level Rise Projection, Elevation Data Is the Key . . . • 2009 National Research Council report “Mapping the zone: Improving Flood Map Accuracy” Topographic/bathymetric data is the most important factor in determining the accuracy of flood maps • Climate Change Science Program SAP 4.1, “Coastal Elevations and Sensitivity to Sea-Level Rise” Sea level rise mapping requires high-resolution elevation data (Current national datasets {30m DEMs} are not adequate)
