Description:
Abstract:
A dataset of shallow water (generally less than 30 m depth) coral reef locations for the Caribbean Sea and Gulf of Mexico at 500 m resolution derived from a variety of sources.
Purpose:
This dataset was developed for the Reefs at Risk Caribbean project (World Resources Institute, 2004 <http://reefsatrisk.wri.org>) and shows locations of coral reefs in the Wider Caribbean

Process_Description:
Maps of coral reefs in vector format (ESRI ArcINFO line and polygon files) are the basis for the coral reef map for the region. These data were of multiple scales, generally ranging from approximately 1:30,000 to 1:1,000,000, and from multiple sources (listed below).

Sources: --University of South Florida, Institute for Marine Remote Sensing (IMaRS), "Millennium Coral Reef Mapping Project," 2004 (30 m Landsat data classified and converted to shapefile) for the Lesser Antilles (British Virgin Islands through Barbados), the Turks and Caicos Islands, Southern Bahamas, Dominican Republic, Haiti, Jamaica, Nicaragua, and Panama).** --US National Oceanographic and Atmospheric Administration (NOAA), "Benthic Habitats of Puerto Rico and the U.S. Virgin Islands," 2001, from high-resolution aerial photography. --Coastal Zone Management Institute of Belize, 1999. (30-m Landsat data classified and converted to shapefile, for Belize). --For other areas, UNEP-WCMC "Coral Reef Maps," 2002. Data have been acquired or digitized from a variety of sources. Scales typically range from 1:60,000 to 1:1,000,000. --In addition, WRI edited and digitized maps for some areas based on input from project partners.

(**The Millenium Coral Reef Mapping Project developed a geomorphologic classification of coral reefs. To make data comparable to other map sources, the Reefs at Risk project selected a subset of 30 categories from the overall mapping effort. Categories with high probability of being living coral -- such as forereef, inter-tidal reef flat, barrier reef pinnacle, and shallow terrace -- were included, while categories such as drowned bank and undetermined envelope were excluded.)

To standardize these data, WRI converted them to raster format (ESRI ArcINFO GRID) at 500-m resolution and projected in Lambert Azimuthal (-76,16) for use in the analysis.
