Seward Peninsula Landsat MSS Classification (Thayer-Snyder 2000)
The Landsat Multi-Spectral Scanner (MSS)-derived Seward Peninsula land-cover map was created to supply a detailed land-cover map for two National Science Foundation funded projects: the Arctic Transitions in the Land-Atmosphere System (ATLAS) project, and the Circumpolar Arctic Vegetation Map (CAVM) project.
The map extent is the entire Seward Peninsula west of an arbitrary line drawn between the Elephant Point to the north, and the Koyukuk River Delta to the south. The study area is approximately 50,000 square kilometers.
The map is a raster map (tif), showing a preliminary, unsupervised Isoclass classification of a mosaic created by the US Geological Survey EROS Data Center in 1999. The report (Raynolds et al 2002) describes a comparison with two other maps, the Soil Conservation Service Range Mapping (Swanson et al 1985) and the Major Ecosystems of Alaska (Joint Federal-State Land Use Planning Commission 1973). The legend includes 6 vegetation classes, water, barren, snow and ice, and shadows.
