Description:
Abstract:

The USGS National Stream Quality Accounting Network (NASQAN) program studies the water quality of large rivers of the United States. From 2001 to 2005, NASQAN will study the water quality of the Yukon River. Located in Canada and Alaska, the Yukon River drains approximately 330,000 square miles and is the fourth largest watershed in North America. As part of this water quality study, a number of Geographical Information System (GIS) data sets are being created.

Purpose:

The purpose of the GIS datasets of the Yukon River Basin is to provide scientists working on the Yukon River study the information needed to do basic spatial analysis.This GIS coverage is one of 16 coverages created for the Yukon study.

Supplemental_Information:
Procedures_Used The digital elevation model for the Yukon River Basin was created by obtaining GTOPO30 data from the USGS EROS Data Center in Sioux Falls, South Dakota. GTOPO30 is a global digital elevation model. Elevations in GTOPO30 are regularly spaced at 30-arc seconds (approximately 1 kilometer). Once the GTOPO30 data were obtained, the Yukon River DEM was created by clipping the GTOPO30 dataset with the watershed boundary of the Yukon River Basin. The resulting grid was then projected into an Albers Equal Area projection with the following parameters:

Projection ALBERS Units METERS Datum NAD27 Parameters: 1st standard parallel 55 00 00 2nd standard parallel 65 00 00 Central meridian -154 00 00 latitude of projection's origin 50 00 00 false easting (meters) 0.0000 false northing (meters) 0.0000
