Description:
Abstract:
Digital ecosystem information portraying the location and boundaries of the ecosystems. The Service originally chose the U.S. Geological Survey's Hydrologic Unit Map as the foundation for delineating ecosystem unit boundaries on a national scale. Since that time, boundaries in some of the regions have been moved to the closest county boundaries to simplify management responsibilities. The current unit boundaries reflect this combination.
Purpose:
The data were used to create the JPEG graphics that are being used to illustrate the ecosystems. It has been edited from the initial coverages that were used for national review, and could be considered a final draft version.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The files have been edited from the initial coverages that were used for national review, and could be considered a final draft version.
Logical_Consistency_Report:
Software capabilities were used to ensure arcs have no dangling nodes and intersection errors and to check polygons for label errors.
Completeness_Report:
The source information provided here should be considered 'final' draft, although most of the known discrepancies have been resolved through the review process. There are still a number of data slivers that need to be processed and cleaned up.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Digital boundary was overlain on USGS 7.5 minute topo. quad(s) (DRG). Data are stored in ArcInfo double precision.

Graphic files in JPEG format illustrating the ecosystems
Process_Step:
Process_Description:
The ArcView files were used to create the JPEG graphics that are being used to illustrate the ecosystems. They have been edited from the initial coverages that were used for national review, and could be considered a final draft version. There are still slivers that are apparent when the regional layers are put side by side; this is caused by the widely varying sources of the data. All the major changes to the data have been made however.
