Below is a summary of the datasets available. To access downloadable ZIP files of this and other Reefs at Risk data, please click here.
Data download options:
- Download Point Data Sets (rrsea_points.zip) reflecting coral reef locations classified by estimated threat. This option provides a zip file including six point data sets, a polygon data set of watershed boundaries (with associated erosion estimates) and a polygon data set reflecting country boundaries. (The six threat estimates are for the individual threats - coastal development, marine-based pollution, overfishing, destructive fishing, and sediment and pollution from upland sources, in addition to integrated threat – the Reefs at Risk threat index.) The zip file also includes an ArcView project file (rrsea_pt.apr) which requires ESRI’s ArcView software. The zip file is 25 Mbyte.
- Download GRID Data Sets (rrsea_grids.zip) reflecting threat estimates, and coral reef locations classified by threat estimate. This option provides a zip file including 17 grid data sets, a polygon data set of watershed boundaries (with associated erosion estimates) and a polygon data set reflecting country boundaries. The grid data sets include both a threat surface (a threat estimate for all areas) and reef locations classified by the threat estimate for each of the threats considered. These are coastal development, marine-based pollution, overfishing, destructive fishing, and sediment and pollution from upland sources, in addition to integrated threat - the Reefs at Risk threat index. The zip file also includes an ArcView project file (rrsea_gr.apr) which requires ESRI’s ArcView software and Spatial Analyst 2.0 extension. The zip file is 24 Mbyte.
Notes on unzipping
For the GRID data to work, it is important that the data retain the directory (path) structure that they were saved with. This happens automatically with the WinZip Software. If using PKUNZIP, it is important to use the “-d” option of the command. These data should unzip into a directory called \reef_wri\data_mer\. For the ArcView project to correctly reference the data locations, it is best to unzip these data onto the c:\drive.
