Automatic Daily Tracking

Automatic Daily Tracking (a checkbox in the "etc" Toolbox tab) ensures that the trackpoints collected throughout a single day (midnight to midnight in local zone time) are stored and managed as a single (possibly multisegment) track.

If the Automatic Daily Tracking checkbox is selected, the "Toggle Tracking" tool will - as before - turn tracking on and off. However, on turning it off, the accumulated track will be extended with the previous one, if it does not extend into yesterday. Disjoint segments are kept separate, time-adjacent segments are merged into a single segment.

Every Midnight the tracking is turned off and on again automatically, to ensure that the track does not span dates.

If Automatic Daily Tracking is selected during the day, when some tracks have already been created, only the last one will be merged with future daily tracks.

Assuming Automatic Daily Tracking is on, normally during tracking periods there will be two tracks visible in the Route Manager: the current track (red colour trackpoints on the chart) and the previously accumulated track for the day. After toggling tracking off there will be just one track for this day.

If the timezone needs to be changed, it is a good idea to close OpenCPN application before..

With the manual capability of splitting and extending, the daily tracks can be easily managed at any time.

Without Automatic Daily Tracking selected, OpenCPN handles tracks as before.

For tracks without explicit names Route Manager displays names consisting of starting timestamp (in UTC). It is highly recommended to develop some own habit for assigning names.

It is good to remember the LOGBOOK feature, unconditionally writing half-hourly timestamps into the file opencpn.log. These can be extracted, manually or using the special tool Pavel published for us Forums - Post 563135">here.
