Geographic Coordinate Formats
Geographic coorinates can be entered in either decimal degrees or degrees, minutes and
seconds (the minutes and seconds are optional). Northern latitudes and eastern longitudes
are positive and southern latitudes and western longitudes are negative. Direction
designations of "N", "S", "E" or "W" can also be
used. For example, all of the following refer to the same latitude:
- N40D 43M
- +40.716666
- 40.716666
- 40 43
Similarly, all of the following represent the same longitude:
- W73D 59M
