Dr. Dar A. Roberts


Dr. Roberts is an Associate Professor in Geography at the University of California, Santa Barbara, where he started in January 1994. He is the author of 19 refereed publications, 10 books/book chapters and over 80 abstracts and non-refereed articles. Research interests include sensor fusion, change identification using multitemporal remote sensing, imaging spectrometry, spectroscopy and wildfire hazard assessment. He has worked with hyperspectral data since 1984 and broad band sensors such as MSS and TM over the same period. More recently he has been working with Synthetic Aperture Radar, starting in 1996. He is the UCSB Principal Investigator of the Southern California Wildfire Hazard Center and leads the group in developing wildfire fuels maps and mapping fuel moisture using remote sensing. Courses he teaches includes Land Surface Process, Environmental Optics, and Advanced Remote Sensing in the Optical (214a) and Microwave (214b). Publications directly related to wildfire or techniques used to map fuels include:
