However, it may inaccurately classify snow and ice as water, posing a limitation in certain environments. - This is only used when not enough sand pixels are detected within the reference shoreline buffer. 2025-09-01 00:06:37,391 - satellite_download_logger - INFO - --------------------------------------------------------------------------------------------------------------------- 2025-09-01 00:06:37,392 - satellite_download_logger - INFO - Extracting shorelines for L5 Minimum Shoreline Length: 500 2025-09-01 00:06:37,394 - satellite_download_logger - INFO - WARNING: CoastSat has hard-coded the value for the minimum shoreline length for L7 to 200 2025-09-01 00:06:37,394 - satellite_download_logger - INFO - Extracting shorelines for L7 Minimum Shoreline Length: 200 2025-09-01 00:06:37,395 - satellite_download_logger - INFO - Extracting shorelines for L8 Minimum Shoreline Length: 500 2025-09-01 00:06:37,406 - satellite_download_logger - INFO - L8 2025-08-20-21-53-43 cloud cover : 9.62% 2025-09-01 00:06:37,504 - satellite_download_logger - INFO - L8 2025-08-20-21-53-43: sand: 0.39% ,whitewater: 0.85% ,water: 50.95% 2025-09-01 00:06:37,505 - satellite_download_logger - INFO - L8 2025-08-20-21-53-43: Greater than 50 sand pixels detected within reference shoreline buffer.
