There is currently no way to list all elements in a GEO index. We can of course abuse the knowledge of how it is implemented, but that won't help us parse the score into a lat/long. It is probably possible to abuse GEORADIUS to do this by asking for everything within all-the-miles of 0/0, but it would be nice not to have to. Not sure whether this should be GEORANGE or GEOSCAN (if you see what I mean), but key point is to yield member, lat, long in some way.
Can't believe I cannot label issues from the mobile site :-(
Bottom of screen "desktop version" - awkward but works
