Everyone can see the coordinates unless the taxon is threatened.
Public coordinates shown as a random point within 10KM of the true coordinates. True coordinates are only visible to you and the curators of projects to which you add the observation.
Coordinates completely hidden from public maps, true coordinates only visible to you and the curators of projects to which you add the observation. Observations with private coordinates will still be used to verify place check lists.
