Vegetation and a Landsat-Derived Land Cover Map of the Beechey Point Quadrangle, Arctic Coastal Plain, Alaska
This report presents a Landsat-derived land cover classification of the Beechey Point, Alaska, 1:250,000-scale quadrangle with descriptions of the major vegetation units. Eight Landsat-level units derived from multispectral scanner data, eleven photo-interpreted units, and eight common vegetation co...
