Hey there. As part of our efforts to make uploading better, I spec'ed
out a Geolocation widget. It will probably first appear in UploadWizard
http://www.mediawiki.org/wiki/Extension:UploadWizard/Location
Your next question might be, when is UploadWizard being released for
real? We plan to be have something that can go live to many users by the
end of this month. See the other post I'm making about UploadWizard's
release.
