We thank Laurie Gibson, David Suter, and Alireza Bab-Hadiashar for their helpful discussions on image analysis. We gratefully thank the staff at the Northwest Territories burns for their assistance collecting these data, particularly Bob Schuette, Paul Sopko, and Jack Cohen, who scaled the USFS tower to mount the camera. The assistance and advice of Dr. Brian Stocks of Forestry Canada were invaluable. We also thank the Mathematics Department at Monash University for the use of their local computing system, which was used to perform this analysis. One of the authors, J. Coen, is supported under USDA Forest Service Research Joint Venture Agreement INT-97034-RJVA. Special thanks also to Inframetrics for their technical support and to Dr. Robert Serafin (NCAR director) whose support helped foster this line of research.
