North Slope Alaska Lake Inventory Water Classification; USGS, Alaska

North Slope Alaska Lake Inventory Water Classification is a digital data set
containing water classification images that can be output to 1:250,000 and
1:63,360 scale maps and text files with the following lake attributes per
1:250,000 scale quadrangle: unique lake number, acre size of a particular lake
class (such as shallow, turbid, deep, and ice), latitude/longitude of the lake
center, lake depth, and comments. 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.
