"Understanding Landscapes Using Digital Topography"

Geomorphometry is the field of study concerned with the representation and quantitative analysis of topography. The discipline focuses on extracting information from digital elevation models (DEMs) to better understand landscape processes. As a sub-discipline of geomatics, geomorphometry draws upon the methods and theories of geographical information science, spatial analysis, geocomputation, image processing, and remote sensing. Over the past few decades, improved terrain modeling technologies and processing techniques have underpinned many advancements in soils and vegetation mapping, hydrological modeling, sediment transport modeling, slope stability analysis, geological resources inventorying, and numerous other environmental applications.

Together with my colleagues and graduate students, I explore applications of geomorphometry to spatial hydrology (hydrogeomatics) and geomorphology. I am particularly interested in applications involving airborne laser scanning (airborne LiDAR) and terrestrial laser scanning (terrestrial LiDAR). The use of DEMs to model surface drainage patterns, including the handling of topographic depressions in flow-path modeling, has been a career-long research theme. My research projects often involve the development and testing of novel techniques for spatial analysis and as such I have developed open-source GIS software to serve as platforms for these research contributions.

My research program has spawned a successful startup compnay, Whitebox Geospatial Inc., that focusses on the ongoing development of the WhiteboxTools geospatial analysis software and supporting its global user community.
