Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.0001. Longitudes are given to the nearest 0.0001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.
The flattening of the ellipsoid used is 1/298.257.
The National Ocean Service is conducting research to digitally map biotic resources and coordinate a long-term monitoring program that can detect and predict change in U.S. coral reefs, and their associated habitats and biological communities. This project was conducted in support of the U.S. Coral Reef Task Force (<http://coralreef.gov>).

Person who carried out this activity:
All of the imagery is horizontally positioned to less than one Landsat multispectral pixel (28.5 meters). Spatial data meets or exceeds national map accuracy standards for fixed features.
Landsat imagery over deep water has been removed.
Multispectral Landsat satellite imagery was positioned using National Geodetic Survey ground control data or Landsat satellite ephemeris data.
Are there legal restrictions on access or use of the data?
- Access_Constraints: none
