AB: LiDAR data were collected before and after a prescribed burn of sagebrush rangeland in eastern Idaho in the fall of 2005. These data were processed to filter vegetation points from bare earth and calculate the vegetation heights. The pre-fire and post-fire vegetation heights, as well as derived surface texture products, were compared to determine the amount of burned vegetation and calculate burn severity indices. The resulting classifications were then validated using field data from the burn site. While all products clearly reflected variations in burn intensity, the change in surface roughness was found to most accurately reflect the field- measured burn severity.
