Compare two projection dictionaries for “close enough” equality.

polar2grid.resample._resample_scene._get_legacy_and_yaml_areas(grid_configs: list[str, ...]) → tuple[polar2grid.grids.manager.GridManager, dict[str, pyresample.geometry.AreaDefinition]]

polar2grid.resample._resample_scene._get_preserve_resolution(preserve_resolution, resampler, areas_to_resample)

Determine if we should preserve native resolution products.

Preserving native resolution should only happen if:

1. The ‘native’ resampler is used

2. At least one of the areas provided to resampling are ‘MIN’ or ‘MAX’

3. The user didn’t ask to not preserve it.

polar2grid.resample._resample_scene._is_native_grid(grid, max_native_area)

Check if the current grid is in the native data projection.

Resample a single Scene to multiple target areas.
