Entering Latitudes and Longitudes 

Entering Latitudes and Longitudes

Longitudes and latitudes must be entered in degrees and minutes with an indicator of which hemisphere they are in. Entered latitudes must be geographic (ie. geodetic), rather than geocentric. (Atlases always give geographic latitudes).

Longitudes and latitude must have at least two elements:

•

A degree number (ie. 0 to 180 for longitude, 0 to 90 for latitude)

•

A hemisphere code (ie. E or W for longitude, N or S for latitude)

 

Optionally there may also be

•

A minutes of arc number (ie. 0, 1, 2, 3, ..., 59)

•

A seconds of arc number (ie. 0, 1, 2, 3, ..., 59)

 

Separators between the elements within the time may be any of the following:

      blank( ); slash(/); period(.); colon(:); semi-colon(;) or comma(,)

 

Some examples of valid longitudes are as follows.

 

0W                0W0                149E38                        78W23 45                E 167 52

 

Some examples of valid latitudes are as follows.

 

0S                0N0                17S58                        62N17 59                S 45 23
