Remote Sensing Techniques Aid in Preattack Planning for Fire Management


Book Description

Remote sensing techniques were investigated as an alternative for documenting selected preattack fire planning information. Locations of fuel models, road systems, and water i sources were recorded by Landsat satellite imagery and aerial photography for a portion of the Six Rivers National Forest in northwestern California. The two fuel model groups used were from the 1978 National Fire Danger Rating System and the Northern Forest Fire Laboratory. Landsat-derived fuel model data were digitized and computer analyzed by unsupervised and guided clustering techniques to produce a fuel model map of the area. Overall Landsat classification accuracies of fuel models were moderate-71 percent. This was mainly due to the incompatibilities found between fuel model descriptions and remote sensing capabilities. The results suggest, however, that a basic preattack plan that is moderately reliable, quickly attainable, and easily updated is feasible by applying remote sensing techniques.
