Data can be keyed on a U.S. Geological Survey 1:250,000 basis. Spatial referencing is by 50 meter grid cell size. Data source is Landsat MSS landcover classifications. This data set contains 54 records. The file structure is sequential. Subsets and custom formats are available. Limited documentation is available. Data is used to locate deep lakes for human use and in gas/oil exploration during the winter months. Data can be output to 1:250,000 and 1:63,360 scale maps and text files. General area covered is the North Slope of Alaska north of 69th parallel. Data is organized by 7 1/2 ' or 15 ' quads.
