Motivation

[edit]

In the discussion at Wikidata:Property proposal/planetary coordinates, we identified a series of problems with using coordinate location (P625) for places on the Moon (among other non-Earth bodies):

  • Method varies from one astronomical body (planet/satellite/asteroid/) to another
  • Wikimedia functions for maps don't all correctly check for globe and generally need custom code to "exclude" non-Earth locations.
  • Users might incorrectly assume that P625 is the only property for coordinates. However, we already have a series of separate properties for places on Earth and a group of properties for celestial coordinates
  • Wikidata Query Server has some handling of globes, notably functions have a globe parameter. However, the globe needs to be hard-coded and distance adjusted for the globe. Accordingly, queries need to be globe specific

Also:

  • Interface doesn't support setting globes
  • Current application at Commons has a problem with the inclusion of places on the Moon in coordinate location (P625)
  • Applications working with both Earth and moon coordinates on WMF sites seem rare (or inexistent)

@ArthurPSmith, Paperoastro: can you help me complete the proposal? (Add your motivation for this property here.) --- Jura 21:07, 18 November 2020 (UTC)[reply]
