New Maps from Allen Coral Atlas

Hello from the Allen Coral Atlas Team!

The Allen Coral Atlas announces two newly mapped regions: Southeast Asian Archipelago (including all of Indonesia) and the Coral Sea. This brings us to over 311,000 km2 mapped, and counting!

Please join us during the month of March for a live mentored course covering three lessons of Remote Sensing and Mapping for Coral Reef Conservation Online Course! This will include a weekly three-part instructive webinar series to provide guidance on the course, supplemental material, and participant questions forum. Create a  free login and register here.


Regions coming next:

Central Indian Ocean

Great Barrier Reef & Torres Strait

Western Australia

South China Sea



Other New Atlas Features:

Dynamic Brightening Monitoring System now available for Hawaii

Dynamic Turbidity Monitoring (quarterly) available for download

Bathymetry data layer available for download

Satellite imagery mosaics 2018-2020 available for download

NOAA Coral Reef Watch Data layer is now available in a time series - see data from October 2018 to Present

Suggestion for correction/s

Any additional information (Reef name(s), data in kml, shapefile, or JSON format, detailed  explanation of the error, any relevant field data)


Although not all changes are guaranteed to be implemented, feedback helps to improve the automated mapping algorithm and will improve our overall accuracy.


We look forward to hearing from you! Get in touch at [email protected]

Thank you,

Overview: The Allen Coral Atlas partnership is developing cutting-edge technology to, for the first time, create an accurate global mosaic view of coral reefs from high resolution and frequent satellite images of reefs. As the Atlas develops maps of benthic habitat and reef geomorphology regionally and then globally, the field engagement component seeks to identify sources for calibration/validation data and also enable users of the Atlas to achieve conservation results (e.g., through marine spatial planning, restoration, coastal monitoring, and better management). The Atlas is funded primarily by Vulcan Inc. (founded by the late Paul G. Allen); partners include Planet Labs, Arizona State University’s Center for Global Discovery and Conservation Science, the National Geographic Society, and the University of Queensland’s Remote Sensing Research Center (RSRC).
