Tracklog

The Tracklog tab is used to specify data logging settings for the GPS Tracklog file. The GPS Tracklog file is a PointZ shapefile (shape type 11). If the GPS Tracklog is currently active, any changes made on this tab are not applied until the GPS Tracklog is deactivated.

Filename

Tap to choose the shapefile you want to use as the GPS Tracklog file.

The default is TrackLog.shp in the My Documents folder.

# Entries

This displays the number of GPS points currently stored in the GPS Tracklog file displayed in the Filename field.

This is a display-only field.

Clear

Tap this button to delete all GPS points from the GPS Tracklog file displayed in the Filename field.

Interval (secs)

Type the logging interval for the GPS Tracklog file. For example, an interval of 3 means that every third GPS position will be stored in the GPS Tracklog file.

The default is 1.

Apply GPS Quality Rules

When checked, the GPS quality rules specified on the Quality tab of the GPS Preferences dialog box are applied to GPS points being stored in the GPS Tracklog file. For example, if 3D Mode Only is checked on the Quality tab, only 3D GPS points are stored in the GPS Tracklog file.

The default is checked.

Measure

Choose the GPS measurement that will be used for the measure value (m-value) of GPS points stored in the GPS Tracklog file. The default is PDOP.
