A Description of the four sites with long-term shoreline change datasets used as benchmarks. B The five SDS algorithms evaluated in this study and their outputs. C The evaluation methodology; all algorithms were evaluated against the groundtruth observations of the MSL contour. CoastSat, SHOREX and CASSIE provide instantaneous shorelines from individual satellite images for which we could compare the Landsat and Sentinel-2 accuracies as well as the effect of wave setup corrections. The full methodology and benchmarking software are publicly available at https://github.com/SatelliteShorelines/SDS_Benchmark.
