PN 022516-504 (12/19) Above: The eCognition-based classification and map of the benthic habitats across the 237 Cairns/Cooktown (CC) reefs, a group of northern GBR reefs about 10 to 50 km offshore that are in dire condition Left: Branching coral just underwater surface captured on the reef flat of Heron Reef, Southern Great Barrier Reef Australia Photo: C.Roelfsema eCognition-based reference dataset of 300 reefs, they created a set of training and validation points. Those points were fed into GEE's machine-learning classifier to classify and produce a geomorphic map of the whole GBR. They then applied OBIA neighborhood rules to strengthen the map results. In October 2019, they presented the premiere GBR geomorphic map to the GBRMPA; the final map was delivered in December. In 2020, the team will refine the map to classify and map the GBR's benthic communities; and in 2021, they will layer in specific coral types. All maps will be publicly available through the GBRMPA. "This map has been a dream come true," said Roelfsema. "We're providing more detail than scientists have ever had before. Now they'll be able to make spatial, ecological and biophysical connections that they haven't been able to before. And it's only going to get better."
