This presentation will cover digital elevation model generation, terrain analysis tools, and terrain analysis applications that aim to advance our knowledge and management of environmental systems. Topics include how terrain attributes can be used to model the complex spatial patterns of environmental systems over large areas, a description of the terrain analysis algorithms incorporated in ArcGIS and other software packages, and details such as the quirks of particular digital elevation data sources and algorithms, interpretation of terrain attributes, use of terrain attributes in predictive models, and the effects of scale and resolution.
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.
