Multitemporal, small-format 35-mm aerial photo-band. Classifications using all four spectral bands (blue, green, red, and infrared) and four dates (05/23/97, 06/ graphs were combined in a coregistered database to de-23/97, 10/11/97, and 10/30/97) provided the best classifitermine the relative value of spectral and phenological incation accuracies. Variable canopy illumination made formation for overstory tree crown classification of digital classification of individual trees complex. A

A onehood Ratio test confirmed that the number of spectral hectare study site, located in a second-growth forest 15 bands included in the classification procedure (spectral km east of Morgantown, West Virginia, USA, was photoresolution) and the number of dates (temporal resolution) graphed from a light aircraft nine times from May to Ocsignificantly influenced the ability to identify tree species tober 1997 using both true-color and false-color infrared correctly. This study suggests that although multispectral film. Using this imagery, differences in the spectral propdata appear to be more valuable than multitemporal erties and timing of phenologic events between tree spedata, it may be possible to compensate for the limited cies made it possible to discriminate four deciduous tree spectral resolution of planned high-resolution sensors by species, namely Liriodendron tulipifera, Acer rubrum, combining multiple dates of low spectral resolution im-
