Full Citation Examples
NOAA's Office of National Marine Sanctuaries serves as the trustee for a national network of underwater parks encompassing both marine and Great Lakes waters from Washington state to the Florida Keys, and from Lake Huron to American Samoa. The network includes a system of national marine sanctuaries and marine national monuments. Few places on the planet can compete with the diversity of the National Marine Sanctuary System, which protects America's most iconic undersea natural and cultural resources. The system works with diverse partners and stakeholders to promote responsible, sustainable ocean uses that ensure the health of our most valued ocean and Great Lake places. By investing in innovative solutions, we strengthen these iconic places to address 21st-century challenges while supporting America's commerce and tourism. These unique locations inspire people to visit, value, and steward our nation's iconic ocean and Great Lakes places.
The legal boundaries of the national marine sanctuaries are defined within the Code of Federal Regulations, at 15 C.F.R. Part 922 and the subparts therein. The GIS compatible digital boundary files for each national marine sanctuary are representations of those legal boundaries and are based on the best available data.
These files are provided to promote an understanding of the boundaries, locations, and extents for each national marine sanctuary. They are based on the legal definition of each sanctuary as defined in the Code of Federal Regulations, at 15C.F.R. Part 922 and the subparts therein as stressed previously. These digital files are not intended and should not be relied upon for use in navigation or for legal purposes.

NOAA's Office of National Marine Sanctuaries serves as the trustee for a national network of underwater parks encompassing both marine and Great Lakes waters from Washington state to the Florida Keys, and from Lake Huron to American Samoa. The network includes a system of national marine sanctuaries and marine national monuments. Few places on the planet can compete with the diversity of the National Marine Sanctuary System, which protects America's most iconic undersea natural and cultural resources. The system works with diverse partners and stakeholders to promote responsible, sustainable ocean uses that ensure the health of our most valued ocean and Great Lake places. By investing in innovative solutions, we strengthen these iconic places to address 21st-century challenges while supporting America's commerce and tourism.

| Purpose: |
The legal boundaries of the national marine sanctuaries are defined within the Code of Federal Regulations, at 15 C.F.R. Part 922 and the subparts therein. The GIS compatible digital boundary files for each national marine sanctuary are representations of those legal boundaries and are based on the best available data. These files are provided to promote an understanding of the boundaries, locations, and extents for each national marine sanctuary. They are based on the legal definition of each sanctuary as defined in the Code of Federal Regulations, at 15C.F.R. Part 922 and the subparts therein as stressed previously. These digital files are not intended and should not be relied upon for use in navigation or for legal purposes.

Data Quality
| Accuracy: |
Attributes were standardized by feature type (point, line, and polygon)across all sanctuary boundaries. The values recorded for each attributewere quality assured and believed to be accurate. |
|---|---|
| Horizontal Positional Accuracy: |
Positional accuracy will vary depending on source |
| Vertical Positional Accuracy: |
Positional accuracy will vary |
| Completeness Report: |
Where possible, the entire boundary for the sanctuary is represented by this digital file. |
| Conceptual Consistency: |
The data were topologically cleaned. |

Process Steps
Process Step 1
| Description: |
The geographic boundary coordinates listed within the United States Code of Federal Regulations (CFR) were converted to decimal degrees and a text file was created. A point coverage was then generatedusing ArcInfo GIS. The coverage was projected into the Geographic Coordinate System and overlaid on large scale nautical charts and analyzed with additional data such as adjacent sanctuaries and shorelines. Specific attention was given to analysis of inconsistencies between textual descriptions and listedcoordinates. The polyline files were created using a combination of the coordinate list from the CFR and applicable shoreline vector files. Forpoint files, two methods were used. If the sanctuary had a shoreline component, a polyline to point script was used to create a point for each vertice. If a shoreline component was not present, then the original coordinates from the CFR were used to create a point shapefile. Polygon files were created by converting polylines to polygons.
