Airborne multispectral optical imagery was acquired
over the Camp Lake Assessment Site in east central Alberta on
August 4, 1995 to evaluate the applications of this imagery to
mapping waterfowl habitats and vegetation communities. Two
spatial resolution image sets were acquired: I.S x 1.5 m and 3
x 3 m. The imagery was classified using linear discriminant
analysis and maximum likelihood classification in conjunction
with ground ba~d data. The data suggests that both
resolutions can provide comparabJe classiftcation accuracies.
Classification accuracies are a function of the number of
spectral bands, statistical analysis parameters (clas.'i thresholds),
and image mtering. The results also suggest that the land cover
classes used in the analysis exhibit significant spectral
variability. Degradation of the 12 bit data to 8 bits has little
effect on overall classification accuracies.
