  • distance table is created and/or written with airline distances either with geometrical distance (if distance_type “geom” is chosen as keyword function argument) or with WGS 84 distance from vincenty algorithm (if distance_type “vincenty” is chosen as keyword function argument)
  • distances created with distance_air_lines using vincenty algorithm are relative to motion across geoid
