Abstract
Many common digital terrain analysis techniques are problematic when applied to very high-resolution digital elevation models (DEMs), such as those derived from airborne Light Detection and Ranging (LiDAR) surveys. As many researchers are acquiring LiDAR DEMs to facilitate research in Canada's Boreal regions, new image analysis techniques are required that can exploit the full level of detail observed in these datasets. This talk will present several new quantitative methods for landscape segmentation and analysis using LiDAR digital elevation imagery, with a particular emphasis on the spatial characterization of northern peatlands and forested wetlands. A major focus of the talk will be on the new technique of hydrogeomorphic edge-detection, which provides a flexible and scale-adaptive approach for segmenting landscapes into hydrologic response units. Potential applications in hydrological modelling and ecohydrological prediction will also be discussed
