LIDAR Derived 50-Year Flood-Inundation Maps and Orthophotography of Honduras
by Peter G. Chirico, Michael B. Warner and Emily C. Phillips
These maps show the calculated flood inundation polygons for the 50-year flood, for select municipalities within Honduras overlain upon a USGS digital orthophoto derived from aerial photography. The data shown on these maps were collected after Hurricane Mitch, which affected Central America in 1998, and were designed to assist municipal governments in hazard preparedness and planning.
The 50-year flood depth maps provide a basis for land-use planning and for engineering design of structures near or within the floodplain of each municipality. The orthophotos serve a variety of purposes, from interim maps to field references for earth science investigations and analysis and is useful as a layer of a geographic information system and as a tool for revision of both digital and paper maps. These orthophotos were originally produced to help support to hazard prevention activities and serve as basic level GIS data for municipalities involved in the Mitch reconstruction efforts and to support the municipalities planning efforts.
Together the 50-year flood depth data and the orthophotography provide a framework of scientific data that can be incorporated into decision making processes to support relief and recovery efforts associated with natural disasters.
