Magellan CrossoverGPS POI Manager The Magellan CrossoverGPS POI Manager enables you to transfer custom points of interest files from your computer to your Magellan CrossoverGPS. Before we add any custom POI's to the Magellan CrossoverGPS, you should understand how the POI Manager plots POIs. Latitude Latitude can be expressed by dividing Earth into horizontal segments totalling 180 degrees. Starting at the Equator, or zero degrees Latitude, lines (or Parallels) are drawn in 10-degree increments 90 degrees to the north and 90 degrees to the south. If your location is below the Equator, you are at a South Latitude. 0° 10° 20° 30° 40° 50° 60° 70° 80° Longitude North Latitude 90° (North Pole) Equator 80° 70° 60° 50° 40° 30° 20° 10° 0° South Latitude 90° (South Pole) Conversely, longitude lines can be expressed by dividing Earth into vertical segments totalling 360 degrees. Starting at the Prime Meridian (which is The Royal Observatory in Greenwich, England), or zero degrees Longitude, lines are drawn in 10-degree increments 180 degrees to the West and 180 degrees to the East. If your location is on the western hemisphere, you are at a West Longitude. West Longitude 90° 70° 50° 30° 10° 10° 30° 50° 70° 90° 80° 60° 40° 20° 0° 20° 40° 60° 80° East Longitude Additionally, to narrow down your location further, each 10-degree segment is divided into 60 smaller segments called minutes and, still further, each minute is divided into 60 segments called seconds. To express this in coordinates, the city of Los Angeles is located at 34° (degrees) 03' (minutes) and 08 (seconds) North of the Equator, and 118° (degrees) 14' (minutes) and 42 (seconds) West of the Prime Meridian.
