[Plugin: Geolocation] geo_public

If a post has been manually tagged with geo_latitude and geo_longitude then the link and map does not show on a post.

For Geolocation to show the link the geo_public flag needs to be added, this is in conflict with the recommendations of the codex which states that that meta item is optional

geo_public OPTIONAL
    (int) is the geodata public (1) or private (0)? If value is missing, assume public.
