9.10 Configuring the Coordinate System

The GPS TrackMaker® program supports several coordinates systems such as shown below.
Geographic Coordinates (Angular Coordinates)
Geographic Coordinates (or angular coordinates) are the basis for the familiar latitude and longitude lines found on
most maps. Lines of latitude are circles that are parallel to the equator and one to another. That's why lines of
latitude are also called parallels . Lines of longitude are half-circles that extend from the North Pole to the South
Pole. Lines of longitude are also called meridians .
For latitudes to the south of the equator line (0º), and for longitudes to the west of Greenwich (0º), the values are
negative.
The GPS TrackMaker® program presents geographical coordinates in degrees, through 3 different notations:
Deg (dd.ddddd : decimal degrees): Default notation of the program, using 13 decimals. Depending on the
Windows®' Regional Settings , there would be a dot or comma for the decimal values.
Example: latitude -19,9478667572357 longitude -43,9863802100454
Deg / Min / Sec (degrees, minutes, seconds): Notation that represents the value of the coordinates in
degrees-minutes-seconds. "dd" represents the degrees (from –180 to 180), "mm" represents the minutes (0 to 59)
and "ss" represents the seconds and its decimals (0 a 59.999999''). When writing this notation, insert a space after
the hours, an apostrophe " ' " after the minutes and double apostrophes " '' " after the seconds.
Example: latitude 19 56' 52,32033'' longitude -43 59' 10,96876''
Deg / Min (degrees and minutes): Notation that represents the value of the coordinates in degrees-minutes,
where "dd" represents the hours (or degrees, from –180 to 180), "mm" represents the minutes and its decimals (0
to 59.999999999'). When writing this notation, the User must insert a space after the degrees and an apostrophe "
' " after the minutes.
Example: -19 56,87201' -43 59,18281'
