Entering Latitudes and Longitudes

T3d is equipped with a logical string parser that will allow you to enter latitude/longitude coordinates in various formats.

As an example, say we are interested in entering the following coordinates:

Latitude: 45-09-12 N

Longitude: 111-35-01 W

Long notation

Coordinates may be entered as they are shown above, specifying degrees-minutes-seconds and direction. If no direction is specified, latitudes default to "north", longitudes to "west".

Short notation

Coordinates may be specified in the following shortened notation:

Latitude: DDMMSS

Longitude: DDDMMSS

Where D is the placeholder for degrees, M for minutes, and S for seconds. Our example coordinates would look like the following in short notation:

Latitude: 450912

Longitude: 1113501

Also, T3d will allow the user to specify a direction with short notation:

Latitude: 450912N

Longitude 1113501W

Once again, if no direction is specified, latitudes are considered to be "north", and longitudes "west". Lastly, T3d removes all spaces before parsing the coordinates so the example latitude/longitude could be entered as follows:

Latitude: 45 09 12 N ( or just "45 09 12" )

Longitude: 111 35 01 W ( or "111 35 01" )

Decimal notation

You may also specify latitude/longitude coordinates as decimals, however these are sign dependent with the convention of north being positive and east being positive. In decimal notation our example coordinates would be entered as:

Latitude: 45.153333

Longitude: -111.583611
