Beechey Point Land Cover Classification (Walker & Acevedo 1987)

This map is a Landsat-derived land cover classification of the Beechey Point, Alaska, 1:250,000-scale quadrangle with descriptions of the major vegetation units (Walker & Acevedo 1987). Eight Landsat-level units derived from multispectral scanner data, eleven photo-interpreted units, and eight common vegetation complexes were described and illustrated. Procedures of Landsat analysis, field methods, and cartographic methods were described. The region was divided into four landscape units: flat thaw-lake plains, gently rolling thaw-lake plains, hills, and flood plains. Area analysis of the quadrangle was done according to townships and nine small study areas. The mapping used a hierarchical tundra mapping classification approach. Area-measurement data from geobotanical maps at eight study sites were compared with similar data from Landsat maps of the same sites. The results indicated that Landsat maps yielded area measurements corresponding to broad geobotanical categories.
