Notes
A positive latitude value, greater than 0 to 90, means north of the equator; a negative value, less than 0 to -90, means south of the equator.
A positive longitude value, greater than 0 to 180, means east of a line that runs north and south through Greenwich (London), England (the Prime Meridian); a negative value, less than 0 to -180, means west of the Prime Meridian.
Longitude +180 or -180 is the same meridian and referred to as the Antimeridian. Latitude 0 and Longitude 0 is a point 615 kilometers south of the country of Ghana in West Africa.
Bearing values are greater than 0 to less than 180 (if traveling easterly) or less than 0 to greater than -180 (if traveling westerly). For example, a bearing of 90 would be due east and a bearing of -90 would be due west.
