Gardner) Publication_Date: 2001 Title: Bathymetry Mapping of the West Florida Shelf (Northern Region), Gulf of Mexico (NODC Accession 0001410) Geospatial_Data_Presentation_Form: XYZ ASCII and ArcInfo GRID Online_Linkage: https://accession.nodc.noaa.gov/0001410 Description: Abstract: XYZ ASCII format data generated from the 2001 multibeam sonar survey of the West Florida Shelf, Gulf of Mexico. The data include high-resolution bathymetry and calibrated acoustic backscatter. Purpose: These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) or other software to display bathymetry and backscatter data of the West Florida Shelf, Gulf of Mexico.

The data are cleaned of bad navigation and depth readings. The depth readings are gridded into a common grid. The gridded data are converted to an XYZ ASCII format file (Longitude, Latitude, Attribute) and the gridded data are converted to ArcInfo GRID format using ArcInfo's ASCIIGRID command.
