Description:
Abstract:

nawqa_towns is a point coverage of the towns and cities located in the
Cook Inlet Basin National Water Quality Assessment (NAWQA) study unit in
southcentral Alaska. Locations were determined from 1:250,000 scale maps.
Town name, class, 1990 population, and year of incorporation are items in
in the coverage's point attribute file.

Purpose:

The purpose of nawqa_towns is to give an overview of the number of towns located in the Cook Inlet Basin and their respective populations.

Supplemental_Information:

Procedures_Used:

Locations of towns were digitized from 1:250,000 maps of the Cook Inlet Basin. Information on class, 1990 population, and year of incorporation was obtained from the Alaska Department of Regional and Community Affairs.

Revisions:

Complete as of September 16, 1997.

Reviews_Applied_to_Data:

Tim Brabets and Roy Glass reviewed locations of the towns. An editorial review of the documentation was done by Liska Snyder.
