uxarray.Grid.get_ball_tree#

Grid.get_ball_tree(coordinates='nodes', coordinate_system='spherical', distance_metric='haversine', reconstruct=False)#

Get the BallTree data structure of this Grid that allows for nearest neighbor queries (k nearest or within some radius) on either the nodes (node_lon, node_lat) or face centers (face_lon, face_lat).

Parameters:

  • coordinates (str, default="nodes") – Selects which tree to query, with “nodes” selecting the Corner Nodes and “face centers” selecting the Face Centers of each face

  • coordinate_system (str, default="cartesian") – Selects which coordinate type to use to create the tree, “cartesian” selecting cartesian coordinates, and “spherical” selecting spherical coordinates.

  • distance_metric (str, default="haversine") – Distance metric used to construct the BallTree

  • reconstruct (bool, default=False) – If true, reconstructs the tree

Returns:

self._ball_tree – BallTree instance

Return type:

grid.Neighbors.BallTree
