Description:
Abstract:
This data set consists of the priority watershed boundaries of the U.S. Environmental Protection Agency's Gulf of Mexico Program. The boundaries were generated using the U.S. Geological Survey's 8 digit hydrologic unit data set. The watersheds define the area that are of importance to the Gulf of Mexico Program (GMPO), and were selected according to the GMPO criteria. The watersheds are based on the National Estuary Program (NEP) and the National Estuarine Research Reserves (NERR) project areas.
Purpose:
To display the boundaries of the U.S. Environmental Protection Agency's Gulf of Mexico Program priority watersheds.

Access_Constraints:
It is strongly recommended that these data are directly acquired from the distributor described in the distribution section of this metadata record or from another USGS server and not indirectly through other sources which may have changed the data in some way. The distribuoter makes no claim as to the data's suitability for other purposes.
Use_Constraints:
Acknowledgement of the U.S. Geological Survey, National Wetlands Research Center as a data source would be appreciated in products developed from these data, and such acknowledgement as is standard for citation and legal practices for data source is expected by users of this data. Sharing new data layers developed directly from these data would also be appreciated by NWRC staff. Users should be aware of that comparisons with other data sets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in photo interpretation, mapping conventions, and digital processes over time. The distributor shall not be liable for improper or incorrect use of these data, based on the description of appropriate/inappropriate used described in this metadata document. These data are not legal documents and are not to be used as such.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attribute accuracy is based on the software used and the data entry. For those attribute generated by the GIS software, the accuracy is high. For the attributes generated to indicate the name of the watershed, the accuracy is also high (due to the low number of values.)
Logical_Consistency_Report: Unknown
Completeness_Report:
The data are complete as possible. There are no known gaps or ommissions.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy of the horizontal positions is based on the accuracy of the original data, which is unknown.

Process_Description:
The priority watershed areas were derived from the USGS hydrologic unit code (huc). The selected 8-digit hucs boundaries were dissolved to create the areas. The polygons were then attributed.
