The Atlas aims to provide high-resolution, up-to-date global maps of the world’s coral reefs, and a monitoring system to track changes in coral reefs over time. These and other emerging products of the Allen Coral Atlas support coral reef science, management, conservation, and policy around the world. The Allen Coral Atlas was conceived and funded by Vulcan Inc., a private company founded by Jody Allen and the late Paul Allen with a mission to make and leave the world a better place. The Atlas brings together a team of dedicated scientists, technologists, and conservationists, using one-of-a-kind methodologies. The Arizona State University Center for Global Discovery and Conservation Science leads the Atlas strategy and management, pioneers the reef monitoring system, and creates techniques to process high-resolution satellite imagery provided by the Earth-imaging company, Planet. Atlas partners at the University of Queensland Remote Sensing Research Centre lead the coral reef mapping component of the project, and partners from the National Geographic Society work to engage a broad range of users to successfully adopt the Atlas tools.
