Abstract

We evaluated the use of aerial videography for classifying wetland habitats along the
upper Mississippi  River and found the prompt availability of habitat feature maps to
be the major advantage of the video imagery  technique. We successfully produced
feature maps from digitized video images that generally agreed with the  known
distribution and areal coverages of the major habitat types independently identified and
quantified with  photointerpretation techniques. However, video images were not
sufficiently detailed to allow us to consistently  discriminate among the classes of
aquatic macrophytes present or to quantify their areal coverage. Our inability  to
consistently distinguish among emergent, floating, and submergent macrophytes from
the feature maps may  have been related to the structural complexity of the site, to our
limited vegetation sampling, and to limitations  in video imagery. We expect that
careful site selection (i.e., the desired level of resolution is available from video 
imagery) and additional vegetation samples (e.g., along a transect) will allow improved
assignment of spectral  values to specific plant types and enhance plant classification
from feature maps produced from video imagery.
