National Ocean Service Bathymetric & Fishing Maps as Scanned Images
NGDC (now NCEI) DATA ANNOUNCEMENT NUMBER: 01-MGG-01
The NOS Bathymetric and Fishing maps as digital images on CD-ROM. These are topographic maps of the seafloor. Through detailed depth contours the size, shape, and distribution of underwater features are portrayed. Fishing maps are produced at a scale of 1:100,000. They contain Loran-C rates, distribution and identification of bottom sediment types, and known bottom obstructions in addition to the basic information found on standard bathymetric maps.
The maps are compressed and can be viewed with GeoViewer software: lizardtech.com/geoviewer-pro/overview.
None of the maps from the Topo/Bathy series are included. The Topo/bathy series are detailed multipurpose maps that show the National Ocean Service (NOS) bathymetry and the U.S. Geological Survey (USGS) land topographic information. These maps were cooperatively produced by NOS and USGS and are exclusively distributed by the USGS.
The full-sized scanned images come from originals of up to 36 inches by 48 inches. Color maps were scanned at 300 dpi, and preliminary (black and white) maps were scanned at 400 dpi.
