Description:

Abstract:

This dataset consists of 16 polygons representing river basin boundaries that intersect the State of Georgia. These 16 polygons represent the 14 river basin boundaries defined by the Georgia Department of Natural Resources for use in planning purposes (commonly referred to as "the DNR Basins"). The boundaries were compiled using the 1:24,000 HUC boundaries provided by USGS Water Resources Division - Doraville, Georgia.

Purpose:

To provide a boundary dataset of the DNR Basins at 1:24,0000 scale.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: Basin names have been checked for accuracy and are correct.

Logical_Consistency_Report:

The final coverage was overlaid with the original 1:24,000 scale HUC boundaries to ensure logical consistency and proper spatial registration. The number of records in the .pat and values in the AREA field were inspected to ensure that no sliver polygons were present. Topologically clean.

Completeness_Report:

All HUC8 boundaries intersecting the State of Georgia were used as aggregate ridgelines

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report: 1:24,000 scale per the original USGS HUC boundaries.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: 24,0000

Horizontal_Positional_Accuracy_Explanation:

Positions should be true according to National Map Accuracy Standards (+/- 40 feet, 90% of the time).

Source_Contribution:

7.5' topographic quadrangles were used to verify appropriate DNR basin boundary assignments. Features used for verification included ridgelines, stream names, stream confluences, etc.

Process_Step:

Process_Description:

1:24,000 12-digit HUC boundaries were downloaded from the Georgia GIS Data Clearinghouse, decompressed and imported into ESRI coverage format from interchange (.e00) file format. This coverage was then converted into ESRI shapefile format.

Source_Used_Citation_Abbreviation: Georgia Hydrologic Unit Boundaries 12-digit

Process_Date: 2001

Source_Produced_Citation_Abbreviation: HUC12_Shapefile

Process_Step:

Process_Description:

Using ArcInfo ArcMap 8.2, features / records within the HUC12_Shapefile were selected and encoded with values indicating inclusion within appropriate DNR Basin boundaries. These features / records were then aggregated and dissolved using the desktop geoprocessing menu. DNR Basin boundaries were then checked against USGS 7.5' topographic quadrangles to verify appropriate DNR Basin boundary assignments for each HUC boundary.
