That location is plotted with a GPS location of latitude 0, longitude 0. This is the default GPS location for any sample that does not have a GPS coordinate assigned to it. This happens when the POGO does not have a GPS fix (can't obtain GPS coordinates for its current location).
Before taking a sample, confirm that there is a green GPS status indicator on the bottom left of the sample page. If there is a red X, then the POGO is not generating a GPS position. If the badge has a number of 9 or less, the POGO may know its location, but not to the sub-meter level. Connecting may take up to 10 minutes for POGO to see more than 9 satellites.
We recommend turning on your POGO before you head out to the first zone to give it enough time to acquire satellites.
If the badge remains red, try moving to a wide-open location with no trees or buildings around, and leave the POGO on with the app open for 15 minutes. If the POGO is still not generating a GPS signal, it is possible that the GPS chip or power board has come loose internally in the POGO. If this occurs, please submit a ticket to POGO Support.
