ASF Tools v0.6.0

Added

• You can choose whether the ts (threat score; default) or fmi (Fowlkes-Mallows index) minimization metric is used for the flood mapping iterative estimator:
  • the flood_map console script entrypoint now accepts a --minimization-metric argument
  • the asf_tools.hydrosar.floopd_map.make_flood_map function now accepts a minimization_metric keyword argument
• The flood mapping iterative estimator will ignore waterbodies smaller than a minimum number of pixels (default = 0)
  • the flood_map console script entrypoint now accepts a --iterative-min-size argument
  • the asf_tools.hydrosar.floopd_map.make_flood_map function now accepts a iterative_min_size keyword argument

Changed

• The HydroSAR code (flood_map, water_map, and hand) in asf_tools has been isolated to an asf_tools.hydrosar sub-package
• The asf_tools.hydrosar.flood_map.iterative estimator now runs with a maximum step size of 3 instead of the default 0.5.
• The asf_tools.hydrosar.flood_map.iterative estimator now uses the mean of the iterative bounds at the initial guess.
• the known water threshold used to determine perennial water when creating flood maps will be calculated asf_tools.hydrosar.flood_map.get_pw_threshold if not provided
• get_epsg_code and epsg_to_wkt have been moved fromasf_tools.composite to asf_tools.util
• read_as_array and write_cog have been moved fromasf_tools.composite to asf_tools.raster
• get_coordinates has been moved fromasf_tools.flood_map to asf_tools.util

Deprecated

• The asf_tools.hydrosar sub-package is being moved to the HydroSAR project repository and will be provided in a new pip/conda installable package hydrosar. The asf_tools.hydrosar subpackage will be removed in a future release.

Fixed

• Reverted the special handling of nan values introduced in v0.5.2, now that GDAL v3.7.0 has been released.
