There are different GPS coordinate formats, all containing some combination of degrees, minutes, and/or seconds.
If you have a latitude or longitude that is a single number (such as 18.1324), enter that entire number in the degrees field.
If you have a latitude or longitude that is two numbers (such as 18N 13.134), enter the first number in the degrees field and the entire second number in the minutes field.
If you have a latitude or longitude that is three numbers (such as 18N 13 14.554), enter the first number in the degrees field, the second number in the minutes field, and the entire third number in the seconds field.
To use your current GPS coordinates, click the North arrow icon to the right of the coordinate fields.
To estimate the GPS coordinates using a map, click the Globe icon to the right of the coordinate fields, then click on the location on the map that appears.
