What's Changed

Added:

  • Analysis function collect_ground_track arguments sat_altaz and solar_altaz optionally report satellite and solar altitude/azimuth metrics.
  • Analysis function collect_ground_pixels allows pixel-level analysis similar to ground tracks.
  • Analysis function compute_limb computes the observable limb (maximum extent of viewable Earth).
  • Schema PointedInstrument variables cross_track_pixels, along_track_pixels, cross_track_oversampling, along_track_oversampling enable pixel-level analysis.
  • Schema PointedInstrument methods compute_footprint, compute_footprint_center, compute_projected_pixel_position, get_pixel_cone_and_clock_angle, and compute_footprint_pixel_array refactor utility functions and add pixel-level capabilities.

Changed:

  • Updates analysis function collect_orbit_track to check if a masked area contains each subsatellite point prior to additional computation.
  • Refactors analysis function collect_orbit_track and utility function compute_projected_ray_position to use more vectorized calculations.
  • Updates analysis function collect_ground_track to check if a masked area contains each footprint center point prior to additional computation.
  • Updates analysis function collect_ground_track to compute ground tracks at a designated elevation.
  • Renames utility function _get_footprint_point to compute_projected_ray_position.
  • Refactors Instrument method is_valid_observation argument from targets to target.
  • Refactors utility function compute_footprint_center return type from a Skyfield GeographicPosition to a Shapely Geometry.
  • Replaced memory-intensive cross-product in analysis function collect_ro_observations and utility function compute_projected_ray_position.
  • Fixes a bug in utility function _split_polygon_antimeridian where a ground track footprint could circle the wrong pole if the smallest longitude coordinate is in the opposite north/south hemisphere.
