Abstract:
Present climate-change and ecosystem research studies in Arctic and Sub-Arctic areas have created a high demand for detailed land-cover maps. I produced a preliminary land-cover map of the Seward Peninsula, Alaska, using Landsat Multi-Spectral Scanner (MSS)-derived imagery. I used a multiple scene mosaic furnished by the USGS, EROS Data Center, and an Isoclass clustering algorithm to arrive at 9 broad land-cover classes. The Seward Peninsula Multi-Spectral Scanner Map (MSS) has the following land-cover classes and respective percentages: Barrens (3.4%); Dry Prostrate Dwarf-shrub Tundra (6.7%); Moist Herbaceous Dwarf-shrub Tundra (53.7%); Wet Herbaceous Tundra (8.5%); Moist Lowshrub and Tall-shrub Tundra (16.7%); Spruce Forest (5.6%); Water (5.0%); Snow and Clouds (<0.1%); and Shadows (0.5%). Ancillary data including a digital elevation model and previous land-cover maps of the Seward Peninsula were used to make improvements to the MSS landcover classifications. The MSS map gives a high level of spatial detail that is unequaled by the comparison data sets: the Major Ecosystems of Alaska (MEA) map, and the Seward Peninsula Soil Conservation Service (SCS) map. Comparative graphs show the breakdown of land-cover percentages for each of the three data sets. Additionally, difference matrices were calculated, which provide a quantitative indication of how well the landcover classes of the three data sets overlay each other. The MSS map gives a better representation of the variable spatial distribution of vegetation within the otherwise homogeneous SCS and MEA map landcover designations. Overall, the high level detail provided by the MSS data set offers a superior map for understanding the complex patterns of vegetation distribution on the Seward Peninsula.
Purpose: Landcover classification.
