This is a Raster data set. It contains the following raster data types:
Planar coordinates are encoded using row and column
Abscissae (x-coordinates) are specified to the nearest 5
Ordinates (y-coordinates) are specified to the nearest 5
Planar coordinates are specified in meters
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.

The hard and soft seafloor map previously produced by NOAA Pacific Islands Fisheries Science Center Coral Reef Ecosystem Division is being used to improve sampling techniques for long-term ecosystem monitoring, to guide future ground-truthing operations and to identify coral-rich and species specific environments. By combining this initial product with the shallow-water benthic habitat map produced by NOAA Biogeography Branch, a more complete hard and soft substrate map is produced, which fills in many of the gaps in shallow water.
Data are collected for resource management and research purposes and are tested for internal consistency; however, no effort is made to compare these data to external references or to other published data.
Horizontal positioning system: GPS (SPS) Horizontal position accuracy: 25 meters
These data are believed to be logically consistent though no tests were performed
Are there legal restrictions on access or use of the data?
