[0.0.3] - 2025-09-26

Added

• Filter for disconnected interferograms - we now take the largest connected component within a frame and utilize this to identify SLCs from reference/secondary passes
• Geometry for enumerated interferograms represent the intersection of the reference and secondary passes within the frame geometry.
• Dependency on parquet for testing

Fixed

• Use of Natural earth within geopandas (deprecated useage) - now use contextily for plotting some background tiles for understanding location of interferograms.
• Remove ASF warnings related to geometric searches of frames - orient polygons with shapely using orient_polygon.
• Readme instructions for installation.

[0.0.2]

Added

• Adds pandas to pyproject.toml and environment.yml.
• Ensures minimum shapely version in pyproject.toml.
• Linting of packaging files
• Docstrings in stack.py
• Updated readme with definitions
• Sentinel-1C filtering based on Calibration Date: https://sentinels.copernicus.eu/-/sentinel-1c-products-are-now-calibrated
• Python 3.13 support.

Fixed

• Ensure SLCs are contiguous (in addition to frames)
• Future warning related to pandas grouper
• The syntax within Environment.yml (also added ruff)
• Natural earth world is no longer within geopandas so linked to github url.
• Unit tests now use the latest micromamba action (previous was not supported).

Changed

• Ruff is now linter

Removed

• Removes min version on asf_search.
• Flake8 linting in favor of ruff

[0.0.1]

Initial release of s1-frame-enumerator, a package for enumerating Sentinel-1 A/B pairs for interferograms using burst-derived frames.

Added

• All frame instances are initialized with hemisphere property depending whether centroid is smaller than 0 deg lat.
• Minimum frame coverage ratio (computed in epsg:4326) during enumeration is .2
