Roland Viger holds degrees in geography from the University of Toronto and the University of Colorado-Boulder. After contracting with the USGS Branch of Petroleum Geology as a GIS analyst for the National Hydrocarbon Assessment in 1992, he joined the Water Resources National Research Program in Denver as the GIS lead on the Precipitation-Runoff Modeling System project (now the Modeling of Watershed Systems project). His approaches, software (for example, the GIS Weasel), and training materials for geographic analysis in hydrologic simulation modeling have been used throughout the U.S., as well as internationally. He provides consultation within and outside the USGS and has represented USGS interests to other organizations.
His primary research interests are integrated simulation modeling, spatial analysis for the delineation and characterization of landscape features for modeling, and geoinformatics. Roland is active in the Community of Practice for Integrated Environmental Modeling (CIEM), the USGS Community for Data Integration (CDI), the and in the development of national hydrologic modeling systems. He is currently a member of the USGS Core Science Systems Strategic Science Planning Team.
