Evaluation of Airborne LIDAR-derived Floodplain Mapping

The use of airborne Light Detection and Ranging (LIDAR) data for the construction of topographic models and subsequent use in floodplain mapping is a recently developed approach. In a series of projects related to topographic model construction, the effects of LIDAR collection characteristics (e.g. spatial scale and vegetation phenology) on topographic accuracy and floodplain derivation were examined.
