CoastalDEM® v2.1

Climate Central is pleased to announce the release of CoastalDEM® v2.1, a near-global digital elevation model for ocean coastal areas. CoastalDEM v2.1 has substantially reduced bias and error scatter even compared to its predecessor, CoastalDEM v1.1, making it the best-performing of all leading, publicly-available, global digital elevation models tested. CoastalDEM v2.1 is the result of substantial new investment, new neural network architecture, and additional and improved input datasets. 

CoastalDEM v2.1 now predicts corrections on land with elevations between -10 m and 120 m (CoastalDEM v1.1 was 1 - 20 m) making for much broader coverage of coastal areas.
