To provide co-registered Landsat data sets and tree cover maps to
researchers and other interested users and to provide data that will
facilitate land cover change analysis.
These data sets consist of Landsat TM and ETM+ spectral bands from the
same WRS path and row tile for multiple dates co-registered to one
another and a corresponding tree cover map for each date. We have
used the most recent image as the base unless an orthorectified
dataset was available at the time of classification.
