Coordinates
The following coordinates correspond with sites featured on the Temwen Vicinity Eco-Adventure Map Guide. It is our dream to eventually create a Pohnpei GPS app that could be uploaded to smartphones and other devices, but for now, these points of interest can be entered manually in a hand-held GPS device as needed.
NOTE: All GPS devices have a margin of error. That margin increases with interference — when there is a thick canopy of trees, during bad weather, or when mountains obstruct the satellite link. The geosynchronous satellites employed when navigating on Pohnpei are located low on the southwestern horizon, such that maintaining a strong connection while hiking on the northeast side of a given mountain range can be difficult. Coordinates on the northeastern slopes of mountains are less accurate than in other locations.
