Following are coverages available for use in the final model. All coverages are a 16-USGS quadrangle subset of the ALRIS dataset unless otherwise specified.

Names in parentheses are ALRIS names for the same dataset.
(Pardon the naming differences, but we are trying to make the names 8.3 compliant, and more indicitive of the dataset's content.)
