A little lesson about geographical coordinanted, with the use of fruits as an example:
- a melon cut in two halves is perfect to symbolize the Northern and Southern hemispheres, and this is for latitude;
- an peeled orange is naturally divided into slices, and this is for longitude.
And two little Scandinavian blondes to enjoy the fruit salad of our American watch officer.

And a little extract form Wikipedia to those who want to learn something:

Latitude and longitude
Latitude phi (φ) and Longitude lambda (λ)Latitude (abbreviation: Lat. or (φ) pronounced phi ) is the angle from a point on the earth's surface and the equatorial plane, measured from the centre of the sphere. Lines joining points of the same latitude are called parallels, and they trace concentric circles on the surface of the earth, parallel to the equator. The north pole 90° N; the south pole 90° S. The 0° parallel of latitude is designated the equator. The equator is the fundamental plane of all geographic coordinate systems. The equator divides the globe into the Northern and Southern Hemispheres.
Longitude (abbreviation: Long. or (λ)pronounced lambda) is the angle east or west of north–south line between the two geographical poles, that passes through an arbitrary point. Lines joining points of the same longitude are called meridians. All meridians are halves of great circles, and are not parallel. They converge at the north and south poles.
The line passing through the (former) Royal Observatory, Greenwich (near London in the UK) has been chosen as the international zero-longitude reference line, the Prime Meridian. Places to east are in the eastern hemisphere, and places to the west in the western hemisphere. The antipodal meridian of Greenwich is both 180°W and 180°E. The choice of Greenwich is arbitrary, and in other cultures and times in history other locations have been used as the prime meridian.
By combining these two angles, the horizontal position of any location on Earth can be specified.
