摘要

Limitations in knowledge on the location, extent, and status of coral reefs have led to international calls to improve the mapping of coral reef environments. Ideally, mapping programs will work simultaneously at multiple scales to produce maps quickly and then improve these maps over time. We describe an approach to reef mapping that uses a uniform 1-km dataset (SeaWiFS) as a backbone for global-scale reef mapping and for integrating other higher-resolution remote sensing data. SeaWiFS data were used to produce composite maps of bathymetry. Global reef maps compiled by the World Conservation Monitoring Centre can be overlaid with SeaWiFS data to facilitate comparison and refinement of the maps. Data sets at moderate resolution (e.g. Landsat) and high resolution (e.g. aerial photography) were converted to the same projection. Astronaut photography of Earth is an additional source of moderate resolution (pixel sizes of 30 m or less) remote sensing data that makes a unique contribution to these datasets. We describe the methods used to georeference astronaut photographs for incorporation into ReefBase and the WCMC-SeaWiFS database. Georeferenced astronaut photographs were incorporated as GIS base layers into a prototype for ReefBase: A Global Database on Coral Reefs, and linked to information on coral reef biology, status, exploitation, management and socioeconomics. Finally, the global maps and remote sensing data were made available for interactive searching on a prototype Coral Reef Remote Sensing Web site.
