Also use for surface area?[edit]

Should this property also be used for surface area of, for example, planets? --Yair rand (talk) 03:28, 10 September 2015 (UTC)

@Yair rand: I see no reason why it cannot be used for astronomical bodies. -- Innocent bystander (talk) 18:13, 4 November 2015 (UTC)


Do we have any good standard for how we should describe different types of area? Örebro Municipality (Q297718) for example, has

  • 1,373.02 km2 land area
  • 50.60 km2 lake/river water except the four great lakes
  • 196.97 km2 the four great lakes
  • 0.00 km2 sea water[1]

I don't really know what is best, to create new properties or by adding qualifiers. If I take Trois-Pistoles (Q142151), the Quebec "répertoires des municipalités" give two type of area[1]:
  • 9.66 km2 total area
  • 7.62 km2 land area
It's also easy to have the sea water area of most protected areas in Canada. --Fralambert (talk) 03:06, 5 November 2015 (UTC)
My proposal:
Land area: Use P2046 with P518:land (we have to agree about which item for land though)
Water area: same as above
Sea water area: same as above
River/lake water area: same as above
Special cases, like the Swedish example above: Use special designed items in P518.
Total area: Use P2046 without any P518
