TASK DESCRIPTION There are some celestial bodies that use planetographic coordinates (http://planetarynames.wr.usgs.gov/TargetCoordinates), increasing to the West, and currently Wikidata does not support this system. Example: http://en.wikipedia.org/wiki/Adlinda_(crater) It has coordinates (source: http://planetarynames.wr.usgs.gov/Feature/54): - 48.5 South - 35.6 West Now in Wikidata coordinates are (http://www.wikidata.org/wiki Q2577126): - -48.5 - 35.6 - globe: callisto However, the web interface shows: - 48°30'0.000"S, 35°36'0.000"E (East instead of West) because Wikidata does not manage planetographic coordinates. Sometimes instead in Wikidata celestial bodies with planetographic coordinates (according to the source) use planetocentric coordinates, example: https://en.wikipedia.org/wiki/Asgard_%28crater%29 => 32.2° North, 139.9° West according the source: http://planetarynames.wr.usgs.gov/Feature/420 => but 32.2, -139.9° in Wikidata (https://www.wikidata.org/wiki/Q724438). In this way there is a great confusion among Wikidata items, and among Wikidata and the source. Coordinates are inusable for celestial bodies different from the Earth. It is therefore necessary: - the web interface should allow you to specify the coordinate system (planetocentric or planetographic) - or if this is not possible, it should be clarified which is the one and only coordinate system for all celestial bodies.
