Abstract:
Through a cooperative agreement, the U.S. Geological Survey and the National Park Service produced a land cover map of the Bering Land Bridge National Preserve using digitally processed satellite data to provide baseline information about the nature and extent of land cover resources in the area. A Bayesian classification of two Landsat multispectral scanner and two Landsat thematic mapper satellite scenes was used to produce 15 land cover classes. Following a preliminary classification of the multispectral data sets and minimal application of elevation data, scientists visited randomly selected points in the field during 1995 to obtain information about the study area and conduct a comparability assessment of the land cover map using a ‘fuzzy logic' approach. Field results indicated an initial comparability of 50 percent using a standard omission/commission error matrix when comparing field conditions with the map. However, comparability was increased to 74 percent using a ‘fuzzy logic' approach. Additional ancillary data (surficial geology, soils, elevation, slope, and illumination) were applied following the field activities to increase the usefulness of the land cover map. Both soft-copy (digital file) and hard-copy (final paper map) products were generated. Markon, C.J., and Wesser, S., 1997.

Purpose:
National Park Service contracted with USGS - EROS Alaska Field Office, to produce a landcover map of Bering Land Bridge National Preserve using Landsat Thematic and MSS data.
