The six Allen Coral Atlas Global Benthic Habitat Map classes described below were developed by Roelfsema et al 2013* with input from other coral reef benthic classifications.

The Allen Coral Atlas is a global-scale coral reef habitat mapping project that uses Planet Dove 3.7 m resolution daily satellite imagery (in combination with wave models and ecological data) to create consistent and high-detail global habitat maps to support reef-related science and conservation.
Global Benthic Habitat Maps characterize different coral reef bottom types. These bottom types include communities of living organisms attached to the reef (benthos), as well as sediments and underlying substrate.
The twelve Global Geomorphic Zones mapped by the Allen Coral Atlas are listed below, in logical order from external seaward-facing through to internal coral reef structural features. These zones are known to be fairly consistent across different biogeographic regions, and often associated with regionally distinct ecological assemblages of benthic animals and plants. Moreover, geomorphic classes like these have been shown to be reliable predictors of biological habitat richness and diversity.
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.
The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.
