Description:
Abstract:
This is the 1:2,000,000 streams layer with double line, shorelines, removed such that streams are represented by only their centerline (Ecotrust modified)

Statewide rivers and streams were assembled by Alaksa DNR from eighteen files in the USGS 1:2,000,000 Digital Line Graphs (DLG) dataset. Arc with the attributes MIN greater than 0 are valid rivers and streams. From this DLG rivers dataset, the "Major Rivers" dataset was generated. Please refer to this theme, if the eight major rivers of Alaska are what you need. Coverage was "cleaned" by Ecotrust (D Pray) to remove all arcs with attribute MAJ = 0 (tile line outlines) and clipped to Copper River basin

Purpose:
The purpose for this layer is for mapping rivers at no larger than 1:2,000,000.
Supplemental_Information:
During the detailed review of this layer in preparation for public access, it became apparent the USGS DLG rivers and streams for Alaska dataset is not complete. Several major watersheds in Southwest Alaska are missing. Specific known omissions were Wood River, Kvichak River, Ugashik River, Naknek River, and Egegik River. Subsequent versions of this layer will correct this omission. These rivers and other rivers are not missing from the USGS hydrography layer included in the Digital Chart of the World 1:1,000,000 hydrography database, which is available through Environmental Systems Research Institute.

Process_Description:
Procedures_Used- This coverage contains all DLG streams in Alaska (min ge 3001 and min le 3063. These rivers were reselected from 18 individual coverages stre1-stre18 and then assembled into one coverage. Some linecode edits were performed.

In May 1992 the USGS DLG "streams" were appended from 18 individual coverages stre1-stre18. There was no selection criteria.

Here are the steps to create the initial RIVERS coverage which has undergone some editing for "min" values but not for arcs:

append rivers arc all (stre1 to stre18 are included here) build river arc rename river rivers arcedit rivers build rivers arc arcedit rivers

********************************************************************** The arcedit session on /elias was performed 10-24-92 by SKR. Changes that were made to the rivers "arcs" involved only attribute fixes as follows:
