Recording GPX Data

Understanding

GPX Data

Recording in

MobileMapper

Field

MobileMapper Field allows you to save all the instantaneous

positions computed by your receiver to a GPX file. Here are a

few key points that will help you understand how the GPX

data logging function operates in your receiver:

• As soon as GPX data recording is enabled, every single

position computed is unconditionally saved to a “gpx.gpx”

file stored in \My Documents\Ashtech\. The recording rate

is therefore 1 second. Each position is saved as a distinct

waypoint, irrespective of whether this position is part of

the point, line or polygon feature you are currently

collecting.

• As long as GPX data recording goes on, all instantaneous

positions are saved as waypoints belonging to the same

track segment.

• GPX data recording may be interrupted either by

intentionally disabling this function during a working

session or by quitting MobileMapper Field. If you re-

enable the function during the same working session, or if

you-re-start MobileMapper with the function enabled,

then the next positions computed by the receiver will be

saved as waypoints belonging to a new track segment.

• The gpx.gpx file is an endlessly concatenated file. It

should be transferred to your office computer whenever

needed. Starting a new GPX file implies that the current

one should be deleted.

• GPX data collection is job-independent. Changing job

during a working session has not impact whatsoever on the

recording function.

• A sample of GPX file format is given below.
