distance_from_a_to_b

rojak.atmosphere.regions.distance_from_a_to_b(from_feature, to_feature, distance_measure, num_dim=3, core_dims=None, sampling=None)

Distance from feature A to feature B

For example, to find the distance of a contrail forming region to a turbulent region, then from_region would be a boolean array of where the contrail region is and to_region would be a boolean array of where turbulence is present.

Parameters:

• from_feature (DataArray) – Feature to compute distances from

• to_feature (DataArray) – Feature to compute distances to

• distance_measure (DistanceMeasure) – How distance is measured

• num_dim (int) – Number of dimensions to compute distances over

• core_dims (list[str] | None) – Name of core dimensions to iterate over

• sampling (float | Sequence[float] | None) – Only applicable for Euclidean distance, see scipy.ndimage.distance_transform_edt() for details

Returns:

Array of the closest distance from each point in feature A to feature B

Return type:

DataArray
