Description:
Abstract:
The Alaska Department of Natural Resources (ADNR) has combined
rivers for several Digital Chart of the World (DCW) tiles
into one coverage.  Some edits were made where arcs were missing
(Taku River, near Juneau).  The coverage was clipped to the State
of Alaska boundary.  The islands and river polygons were reselected
out of the coverage for simplification.

The river data were combined from the DNNET
coverages comprising the following 5 degree by 5 degree tiles
for Alaska:

AK 12,22,23,32,33
AL 21,31,32
BK 12,13,22,23,33
BL 11,12,13,21,22,23,31,32,33
CK 12,23,33
CL 11,12,13,21,22,23,31
DK 12,13,22,23

Purpose:
ANDR's prupose for modifying this information was for mapping a
physical base at 1:1,000,000.
Supplemental_Information:
Procedures_Used:
This coverage was taken from ESRI's Digital Chart of the World.  It is
clipped to the State of Alaska.  This data was extracted from the
DNNET coverage for each tile that covers Alaska.   For more info
see - DCW Data Dictionary

Revisions:
02/25/98 - D. Mortenson
Renamed from dcw_rivers or $DCW_RIVERS to rvr1mil.

01/10/97 - M. Gorham
Performed a clean on cover.

12/18/96 - D. Mortenson
Taku River (near Juneau) was missing some of its arcs.  Added some
arcs to fill in where it should be.

To use the ARCs for this coverage:
----------------------------------
UNSEL $DCW_RIVERS line dnlntype = 99
(this will remove all connectors between rivers-lakes
and oceans)

To use the POLYs for this coverage:
-----------------------------------
RESEL $DCW_RIVERS poly type  =  R
(this will select all the RIVER polys)

UNSEL $DCW_RIVERS poly type  =  I
(this will unselect all the ISLAND polys)
