BOREAS TE-18 Landsat TM Physical Classification Image of the NSA
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.3334/ornldaac/431
The objective of this classification is to provide the BOREAS investigators with a data product that characterizes the land cover of the NSA.
Description
A Landsat-5 TM image from 21-Jun-1995 was used to derive the classification. A technique was implemented that uses reflectances of various land cover types along with a geometric optical canopy model to produce spectral trajectories.
These trajectories are used as training data to classify the image into the different land cover classes. Companion files include example thumbnail images that may be viewed and using a convenient viewer utility.
