DEM Derived Alluvial Flood Plain Maps and Orthoimagery of Honduras and Guatemala
These maps show alluvial floodplain deposits that were derived by geomorphic processing of a 30-meter resolution digital elevation model (DEM) overlain upon a USGS digital orthophoto derived from aerial photography for selected municipalites in Honduras and Guatemala. 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.
CTI = ln ( A / tan (beta) )
The CTI was reclassified to display only alluvial plain and recent alluvial deposits and overlain on top of the orthophotography of the area. The resultant maps provide a basis for land-use planning and for hazard mitigation near or within the floodplain for areas that do not have available LIDAR floodplain models.
