Abstract

In 1994, wildfires burned over 117,360 hectares (290,000 acres) of forest land on the Payette National Forest in central Idaho. To assess the impact of the fires on the timber resource, a special mission was planned for NASA's Earth Resources-2 high altitude reconnaissance aircraft. For this project, the aircraft carried a 12 inch lens Wild- Heerbrugg RC-10 aerial mapping camera loaded with Kodak SO- 060 Aerochrome Infrared film. The 1:60,000 scale photography was used to map burn intensity within the gross fire perimeter in high, medium, low and not-burned classes. Polygons were digitized and the digital information was used in the ARC-INFO environment to determine the gross effects of the wildfires on the timber resource. An accuracy assessment was performed by comparing the interpretation to data collected from plots established within the burned area. In this paper, we review the need for the information, the mission parameters, the image exploitation phase, the results of the accuracy assessment and the application of the data to forest management.
