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. 2025-04-08 05:45:44,612 - satellite_download_logger - INFO - --------------------------------------------------------------------------------------------------------------------- 2025-04-08 05:45:44,614 - satellite_download_logger - INFO - Extracting shorelines for L5 Minimum Shoreline Length: 500 2025-04-08 05:45:44,615 - satellite_download_logger - INFO - WARNING: CoastSat has hard-coded the value for the minimum shoreline length for L7 to 200 2025-04-08 05:45:44,616 - satellite_download_logger - INFO - Extracting shorelines for L7 Minimum Shoreline Length: 200 2025-04-08 05:45:44,617 - satellite_download_logger - INFO - Extracting shorelines for L8 Minimum Shoreline Length: 500 2025-04-08 05:45:44,621 - satellite_download_logger - INFO - Processing image L8 2025-03-04-10-05-36 2025-04-08 05:45:44,621 - satellite_download_logger - INFO - L8 2025-03-04-10-05-36 cloud cover : 0.00% 2025-04-08 05:45:44,672 - satellite_download_logger - INFO - L8 2025-03-04-10-05-36: sand: 0.00% ,whitewater: 0.00% ,water: 46.71% 2025-04-08 05:45:44,673 - satellite_download_logger - INFO - L8 2025-03-04-10-05-36: Less than 50 sand pixels detected within reference shoreline buffer.
