Description:
Abstract: This data layer is an element of the Oregon GIS Framework. Ecoregions denote areas of general similarity in ecosystems and in the type quality, and quantity of environmental resources. This map depicts revisions and subdivisions of ecoregions that was compiled at a relatively small scale (Omernik 1987). Compilation of this map, performed at the larger 1:250,000 scale, was part of a collaborative project between the United StatesEnvironmental Protection Agency, National Health and Environmental EffectsResearch Laboratory (NHEERL)- Corvallis, OR., the U.S. Forest Service, Natural Resources Conservation Service, Washington State Department of Natural Resources and the Oregon Natural Heritage Program. The ecoregions and subregion are designed to serve as a spatial framework for environmental resource management. The most immediate needs by the states are for developing regulations, biological criteria and water quality standards, and for setting management goals for nonpoint-source pollution. Explanation of the methods used to describe the ecoregions are given in Omernik (1995), Griffith et al. (1994), and Gallan et al. (1989). This map is a draft product of one of a few regional interagency collaborative projects aimed at obtaining consensus between the EPA, the NRCS, and the USFS regarding alignments of ecological regions.
Purpose: Oregon Ecoregions data assist managers of aquatic and terrestrial resources in understanding the regional patterns of the realistically attainable quality of these resources.
Supplemental Information: 1) All ecoregion and subregion delineations are digitized from theU.S.G.S. 1:250,000 base maps. Prior to digitizing each base map must beinitialized to orient the map and relate it in geographic coordinates tothe surface of the earth. When the registration tics are entered at thestart of digitizing a transformation error of less than 0.003 must be achieved inorder to insure a high level of registration accuracy. The personresponsible for digital data entry completes a data sheet describingcoverage name, date of entry, and whether a topology for the coverage isestablished.2) After each 1:250,000 base map has been digitized, a topologyfor each coverage is established. This function creates unique identities for each polygon.3) Next each base map is tested for polygon errors through aninternal editing function. Errors are corrected for unlabeled polygons,unclosed polygons, or polygons with more than one label. Topology isreestablished for each coverage and tested again until no error areindicated.4) The digital coverage is then plotted at the same scale as theoriginal base map. This coverage is overlaid on a light table with theoriginal and visually inspected for replication of original lines withdigitized lines. Two individuals independently inspect the coverage for accuracy.Revisions:Revision 1. 9/95.This coverage was appended from completed Level IV coverages in Oregon and Washington [Coast Range (completed 9/92), Blue Mountains and Columbia Plateau (7/95), Puget lowlands, Willamette Valley, Cascades,East Cascade Slope, North Cascades and Klamath Mountains ecoregions (6/95)2. 6/96 update coverage. delete 'hatched' areas.
