When you think of the crown jewels of the coral reefs, it’s hard not to think of Australia’s Great Barrier Reef — and now those jewels are on full display in the Allen Coral Atlas, one of the scientific legacies left behind by Microsoft co-founder Paul Allen.

The atlas was unveiled just a couple of weeks after Allen’s death last October, following through on one of the late billionaire’s passions: preserving the world’s oceans. This month’s addition of satellite-based imagery covering 3,000 square kilometers of the central Great Barrier Reef, from Cairns to Cooktown, represents the largest expansion of the atlas to date.

Even after death, the philanthropic initiatives from Microsoft co-founder Paul Allen just keep on coming.

Today the Paul G. Allen Philanthropies and its consortium of partners unveiled the Allen Coral Atlas, a database of satellite imagery and environmental data aimed at mapping and monitoring the world’s coral reefs in unprecedented detail.

The foundation of the atlas is a global mosaic of satellite imagery, acquired starting last year by Planet’s constellation of Earth-imaging satellites. The images document coral reefs at a resolution of 4 meters (13 feet) per pixel.

Other partners — including the University of Queensland, the Carnegie Institute for Science, the Hawaii Institute of Marine Biology and the National Geographic Society — are analyzing and validating the images to produce maps that show reef depth and water color, and discriminate between the reefs and algae, land, rock, sand and rubble.
