Description:
Abstract:
nawqa_roads is a line coverage of the roads in the Cook Inlet Basin
National Water-Quality Assessment (NAWQA) study unit. The coverage was
created using 1:2,000,000 digital line graphs (DLGs).

Purpose:
The purpose of nawqa_roads was to create one of the cultural features the Cook Inlet NAWQA. The coverage indicates the areas of Cook Inlet that are accessible by vehicles.

Supplemental_Information:

Procedures_Used:

A statewide coverage of the road system was obtained from USGS 1:2,000,000 digital line graphs using techniques described by Domaratz and others (1982). The drainage bsin boundaries of the Cook Inlet Basin, developed from 1:250,000 quadrangle maps, were used as the boundaries of this coverage.

Revisions:

Revisions will be made as more data become available.

Reviews_Applied_to_Data:

Roy Glass reviewed the coverage. An editorial review of the documentation was done by Liska Snyder.
