1.5.1.1.4.1.5. polar2grid.filters.resample_coverage module

Filter classes dealing with resampling output coverage.

class polar2grid.filters.resample_coverage.ResampleCoverageFilter(product_filter_criteria: dict = True, target_area: Optional[Union[SwathDefinition, AreaDefinition]] = None, coverage_fraction: Optional[float] = None)[source]

Bases: BaseFilter

Remove any DataArrays that would not have any results if resampled to the target area.

This filter defaults to checking all products. Pass product_filter_critera=None to disable checking for all products. See BaseFilter for other options.

_filter_data_array(data_arr: DataArray, _cache: dict)[source]

Check if this DataArray should be removed.

Returns

True if it meets the condition and does not have enough day data and should therefore be removed. False otherwise meaning it should be kept.

_get_and_cache_coverage_fraction(source_data: DataArray, source_area: Union[SwathDefinition, AreaDefinition], cache: dict) → float[source]
polar2grid.filters.resample_coverage._get_intersection_coverage(source_polygon: SphPolygon, target_polygon: SphPolygon) → float[source]

Get fraction of output grid that will be filled with input data.
