With mobile devices with web and GPS becoming more and more common it would be wonderful if wikipedia had the ability to return pages 'close' to a given location.
Such an application does already exist (but might need to be adapted for mobile devices), made by [[:de:User:Kolossos]] http://de.wikipedia.org/wiki/Wikipedia:WikiProjekt_Georeferenzierung/Wikiped...
example: http://toolserver.org/~kolossos/wp-world/umkreis.php?la=en&lon=13.733333...
rang= is the range in kilometers set map=1 for a simple 2d scatter plot of the links
