The data were topologically cleaned. |
Where possible, the entire boundary for the sanctuary is represented by this digital file. |
GeoPlan relied on the integrity of the attribute information within the original data. |
|
These GIS compatible digital files are provided to promote an understanding of the boundaries of each national marine sanctuary. They are based on the legal definition of each sanctuary as defined in the Code of Federal Regulations, at 15 C.F.R. Part 922 and the subparts for each national marine sanctuary. These digital files are not intended and should not be relied upon for use in navigation or legal purposes. For legal questions relating to the digital files, please contact the NMSP at the information provided in this metadata record. |

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING, MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

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 generated using 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 listed coordinates. The polyline files were created using a combination of the coordinate list from the CFR and applicable shoreline vector files. For point 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.
