caf.space.utils.find_point_matches(gda, gdb, max_dist, *, id_col_1, id_col_2, name_1, name_2)[source]#

Find corresponding point features between two geodataframe.

Finds the nearest point feature from gdA to each feature in gdB, then filters for distance < max_dist.

Parameters:

  • gda (Point geodataframe)

  • gdb (Point geodataframe)

  • max_dist (The max distance two points can be considered as matching, in metres.)

  • id_col_1 (id_col pf gda)

  • id_col_2 (id_col of gdb)

  • name_1 (name of gda)

  • name_2 (name of gdb)

Return type:

gdB with a column for corresponding points in gdA, and the distance between them.
