This report summarizes within-scene variability and spectral relationships of high-resolution, multitemporal, multispectral scanner images of a deciduous forest in eastern Tennessee. The data were obtained using a helicopter-mounted Daedalus D-1268 multispectral scanner with a 1.25-milliradian instantaneous field of view at 175 ft 53.34 m above ground level agl and 350 ft 106.7 m agl. Flights were made under generally clear skies at predawn twilight, mid-morning, and near solar noon in the north and west direction at both altitudes. In the mid-morning and solar noon data, spectral bands of yellow-green, red, near-infrared, and thermal infrared energy were analyzed. Additional thermal infrared data from a Daedalus D-1261 scanner flown at 150 ft 45.7 m agl under overcast skies were also available. Within-scene variability was analyzed to extract parameters for autoregression models of texture for scene modeling and to provide validation data for physically based models of remotely sensed temperature variation of forests.
