Props should go to Helge for the spec. I guess that writing specifications for unmanned aerial vehicles is finally paying off. I presume you are referring to this post: http://mail.jabber.org/pipermail/standards/2008-October/019920.html Arc-minutes are a carry over. We wrote the spec with XEP-0080 in mind and use that as the format for publishing the derived location to the user's geoloc node too. We would prefer to use accuracy in meters. While arc minutes may make sense in a GPS sense, accuracy often has to be implied when using other location means. For example, if the server is receiving Cell-ID beacons and some of the known beacons are identified as within a city an accuracy of 100m could be implied due to a known higher tower density. Trying to apply arc-minutes to this would probably end up just being clumsy and it would be nice to use the same unit of measurement for accuracy.
