This GIS overlay is a component of the U.S. Geological Survey, Woods Hole Science Center's, Gulf of Mexico GIS database. The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata.
This shapefile data layer is intended as an illustrative overlay to the Gulf of Mexico. It contains the bathymetric contour lines, in meters, (200, 1000, 2000 and 300) for the Gulf of Mexico area in a polyline format.

Bathymetry is not to be used for navigational purposes.
These data are NOT suitable to be used for any navigational or legal purpose. The contour line data are in most cases manually digitized from a variety of published or unpublished maps. These data are accessible for making illustrations only. There is NO ASSURANCE of their accuracy, completeness, or precision.
Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution. Please recognize the U.S. Geological Survey (USGS) as the source of this information.

Kim Klitgord did the digitizing of the map. The ASCII data set was later converted to the MAPGEN coast format.
The digitized Gulf of Mexico bathymetry contour vector information has been stored in a format for use with the U.S. Geological Survey's MAPGEN program. The vector latitude/longitude coordinates were extracted from the MAPGEN file with the area coordinates of -99.5, 31.1 and -79.5, 22.5 using program getcoast.

The ASCII vector file generated from the MAPGEN coast files was imported to PCI Remote Sensing Software's Imageworks program. The vector line was checked for digitizing errors using PCI's Imageworks program. Some editing was done to delete spurious nodes and correct for overshoots and undershoots in the line segments. The modified segment was saved and exported in the ARC export format as bathyc.e00 with the nodes recorded as latitude/longitude as signed decimal degrees.
