geolime.operations.drillhole.moving_window_declustering

Classes:

Drillholes(data, metadata)

Functions:

anisotropic_distance([a])

Anisotropic distance between two points according to the anisotropy matrix a.

moving_window_declus(drillholes, diam_x, …)

Compute declustered weights by Moving Window algorithm.

which_in_ball(x[, p, r, distance, scales])

Function to return the indexes of the points which are in a (closed) ball in the Euclidean space.
geolime.operations.drillhole.moving_window_declustering.moving_window_declus(drillholes: geolime.objects.drillhole.Drillholes, diam_x: int, diam_y: int, diam_z: int, var: str, geometry: str)

Compute declustered weights by Moving Window algorithm.

Parameters

  • drillholes (Drillholes) – drillholes to decluster in x, y, z

  • diam_x (int) – ellipsoid diameter in x direction

  • diam_y (int) – ellipsoid diameter in y direction

  • diam_z (int) – ellipsoid diameter in z direction

  • var (str) – variable column

  • geometry (str) – ‘ball’ -> which_in_ball ‘parallelepiped’ -> __which_in_parallelepiped

Returns

Return type

declustered weights wi of each data point i

Note

  • counts the number ni of samples inside

    a moving window centered on point i.

  • weight wi is mv/ni where mv is the mean of all the ni.
