A geospatial inventory of coral reef habitats of Red Sea and Gulf of Aden has been created based on Resourcesat-1 AWiFS data of 2004-2009 period. The four-level classification system for mapping Indian Ocean coral reefs have been applied to map the coral reef habitats of Red Sea and Gulf of Aden. Coral reef habitats of Red Sea and Gulf of Aden have been mapped for one-time with AWiFS data. Each coral reef habitat map represents the reef–typology, intra-reef geomorphological zones and sub-zones and the benthic zones in form of digital annotations within the reef habitat boundary. The Red Sea and Gulf of Aden coral reef atlas comprises of 110 reef habitat maps covering the coastlines of 8 countries. Fringing reefs and its sub-types dominate both Red Sea and Gulf of Aden reef structures. Barrier reef, one true atoll and pseudo-atoll structures have also been found in Red Sea. In an overall analysis, the coral reefs of Red Sea and Gulf of Aden are in near-pristine condition barring the localized impacts of urban and industrial centers located on the coast. Coral reef habitats of Red Sea and Gulf of Aden occupy total area of 15020.66 and 621.11 sq km, respectively.
