This GIS line data set represents depth contours (bathymetry) for the offshore areas of North Florida, Georgia, and the Carolinas, as shown in the National Oceanic and Atmospheric Administration (NOAA) Nautical Chart 11480. FWRI staff digitized the contours off of a clean, wrinkle-free paper chart in 1997, using the most current version of the chart that was available in 1997.
To represent marine depth contours, primarily for small-scale (large area) cartographic purposes.
Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information. These data are not to be used for navigation. User should be aware that later versions of the source charts may be available and that contours may have changed. Consult the most recent paper or digital charts available and appropriate coast pilot.

Please cite the original metadata when using portions of the record to create a similar record of slightly altered data, such as reprojection. If any data are modified or adjusted, please share the edited information with FWC. Users should be aware that comparison with other data sets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in mapping conventions, data collection, and computer processes over time.

All entities and attributes have been identified and documented.
Attributes are logically consistent.
Not all contours present on the chart are included in the vector data set.
Positional accuracy has not been verified by FWRI.
The source chart (11480) provided depth contours measured in fathoms
Contours digitized in ArcInfo off NOAA Nautical Chart 11480 at a 1:449659 scale. FWRI staff converted depth from fathoms to feet.

Each contour contains the attributes FATHOM and FEET, which represent the shallowest contour depth in the respective units. A value of 999 indicates the line is a chart border. The D-coding attributes represent contour values in feet only.
