- Abstract
- An airborne infrared line scanner sensitive to the 3- and 5-micron spectral region mapped 38 forest fires during the 1963, 1964, and 1966 fire seasons. The imagery obtained provided information about the fire perimeter, relative intensity of burning areas, and spot fire location under conditions when smoke or darkness prevented visual reconnaissance. This report describes the operational methods and equipment used, and given many examples of imagery collected. It discusses the radiometric and electronic characteristics peculiar to fire-mapping applications. A unique dual Polariod recording camera was developed to provide quickly available imagery for airdrop to fire headquarters.
