This paper discusses forestry applications of highresolution (1/3 to 1 meter per pixel) digital dataobtained with a new 4 band imaging system.
In the University of Idaho Experimental Forest, early-morning images were collected to map stressed vs. non-stressed conifers. Two cases were examined: man-madestress (a chain saw was used to band the trees) and
stress in sites known to be infected with root rot.Four-band images were collected in the green, red, andtwo different near-infrared spectral bands.
Another project involved collection of images in coniferforests in Oregon and Washington. The high resolutionimagery are being used to characterize proportions ofvarious scene components, and thus facilitate moreaccurate modeling of forest canopy reflectance. Inaddition, the data are being used to observe patterns ofriparian canopy disturbance to evaluate changes in streamchannel conditions. Spectral bands approximating thoseof the first four Landsat TM bands were used.
