Per the discussion at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#Passing_a_location_to_Special:Nearby.3F, several Wikipedia users would like to be able to use [[Special:Nearby]] with an arbitrary location, rather than where their browser thinks they are.
There are two parts to this:
a) Allow linking to "places near XXX", e.g. [[Special:Nearby/44.12,-71.13]]. b) Allow the user to enter a location directly.
Allowing locations to be specified as a longitude or latitude is useful for tools that generate links (e.g. GeoHack), but is not particularly user-friendly. A further enhancement would be to accept the name of an article and use the coordinates on that article. This would allow the entry of many town names, for example.
