# GPS navigation

Different situations of using GPS navigation

Your visitor will be notified at a distance between 150 m and 300 from the gps position indicated for the point of interest.

1\) The point of interest is a very large castle. Your visitors roam the city outside the castle. You must indicate the GPS coordinates of each POI visible directly by the visitor.

2\) A single point of interest in the center of the castle will not be notified to the visitor if it is too far away. 3) You give directions on a remarkable street which contains several POIs. Indicate the GPS coordinates of each POI on this street. If these POIs are less than 150 m away your visitor will see several notifications. he will choose the right one based on what he sees next to him.
