LiDAR has fast become the data source of choice in watershed modeling applications such as flood hazard modeling and mapping. This presentation will introduce the technology, and highlight practical issues associated with its use for watershed modeling tasks. Major limitations as well as advantages of LiDAR will be stressed, and guidelines for procuring the data for watershed modeling applications suggested.
Graeme Aggett is an Assistant Professor at Central Washington University, and director of the Center for Spatial Information. He is currently investigating the utility of LiDAR and high resolution multi-spectral airborne and satellite data for a variety of watershed applications focused on better understanding of fluvial processes, their response to land use change, and floodplain hazard.
