Description:
Abstract:

As part of an interagency agreement between the National Park
Service (NPS) and the U.S. Geological Survey (USGS), basin
characteristics are being determined for a number of watersheds
in National Parks of Alaska. Many of the characteristics are
being determined by use of Geographical Information Systems
(GIS). GIS coverages are being made available to other interested
parties.

Purpose:

The purpose of this data set is to provide the NPS information about the ecoregions of the Kobuk River Basin to do basic spatial analysis. A GIS coverage of the ecoregions of the Kobuk River Basin can be used to determine the type and amount of ecoregions for a given watershed. Each ecoregion represents a distinct type of land based on characteristics such as geology, soils, or precipitation. More knowledge and understanding of the Kobuk River Basin will help the NPS in making sound management decisions.

Supplemental_Information:
Procedures_Used The GIS of the ecoregions of the Kobuk River Basin was created by obtaining a statewide ecoregion coverage of Alaska done by Gallant and others in 1995. Using the ARC/INFO CLIP command and the basin boundary of the Kobuk River Basin, the ecoregions coverage of the Kobuk River Basin were created. The coverage was projected into an Albers Equal Area projection with the following parameters:

Projection ALBERS Units METERS Spheroid CLARKE1866 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

The attribute REGION was used to distinguish the ecoregion. REGION = 3 is Brooks Range, REGION = 4 is Interior Forested Lowlands and Uplands, REGION = 5 is Interior Highlands, and REGION = 9 is Subarctic Coastal Plain. TRANSITION = 1 indicates a transition zone from one ecoregion to another.
