Track History Files
A track history file can contain up to 1,000 or 2,000 track points
saved in the Apollo GPS during use, depending on your model.
The track history can be saved in two different formats, selected
when receiving the track history file from the Apollo GPS.
These formats are the following:
•
User waypoint format
•
Comma delimited latitude and longitude
Each track point in a user waypoint type track file is a line of
text with the following information:
•
Track point identifier
•
Degrees latitude to the nearest 1/1,000th of a minute
•
North or South hemisphere.
•
Degrees longitude to the nearest 1/1,000th of a minute
•
East or West hemisphere
Each track point in a comma delimited type track file is a line
of text with:
•
Degrees latitude to 0.0001 degree resolution
•
Degrees longitude to 0.00001 degrees resolution
