Global Distribution of Coral Reefs (2018)

បោះពុម្ពផ្សាយដោយ៖ Open Development Mekong

This dataset shows the global distribution of coral reefs in tropical and subtropical regions. It is the most comprehensive global dataset of warm-water coral reefs to date, acting as a foundation baseline map for future, more detailed, work. This dataset was compiled from a number of sources by UNEP World Conservation Monitoring Centre (UNEP-WCMC) and the WorldFish Centre, in collaboration with WRI (World Resources Institute) and TNC (The Nature Conservancy). Data sources include the Millennium Coral Reef Mapping Project (IMaRS-USF and IRD 2005, IMaRS-USF 2005) and the World Atlas of Coral Reefs (Spalding et al. 2001).

ភាពទៀងទាត់ While having global coverage, the dataset was compiled from multiple sources with varying scale and quality (outlined in "Metadata_CoralReefs.dbf" included in the package). The dataset has yet to undergo external review.
ជំហាននៃដំណើរ Approximately 85% of this dataset originates from the Millennium Coral Reef Mapping Project, of which 35% was validated (by IMaRS-USF and IRD-Noumea) and 50% remains unvalidated (but was interpreted by UNEP-WCMC). Millennium Coral Reef Mapping Project products (validated or not) are at a consistent 30 m resolution (multispectral Landsat 7 images acquired between 1999 and 2002, http://www.imars.usf.edu/MC/index.html). Additional information regarding methodology and 'validated' and 'unvalidated' polygons can be obtained from http://oceancolor.gsfc.nasa.gov/LANDSAT/HTML/README.html.
