note left of TrackPoint
|
|
As of OpenTracks version 3.15.0, all times are using device time.
|
|
Before that TrackPoint.time contained GPS time (determined by GPS hardware).
|
|
However, start/pause/stop events (also stored as TrackPoints) used device time.

note right of Track
|
|
A track is an ordered collection of one or more segments (i.e., continuous parts of distance covered).
|
|
Segments may be started by a user (i.e., start a track recording, continue a paused track, or resume a track) as well as stopped by the user (i.e., pausing or stopping a recording).
|
|
Also segments may started automatically while recording (i.e., distance to previous location was to large).
|
|
Note that this finishes the previous segment.
|
|
|
|
Segment data is stored as TrackPoints (Type.SEGMENT_START_MANUAL, Type.SEGMENT_START_AUTOMATIC, or Type.SEGMENT_END_MANUAL).
|
|
Trackpoints with Type.SEGMENT_START_AUTOMATIC also mark the end of the previous segment.
|
|
All TrackPoints of Type.TRACKPOINT belong to the segment started by the prior TrackPoint with Type.SEGMENT_START_(MANUAL|AUTOMATIC).
|
|
Trackpoints of Type.SEGMENT_START_MANUAL or Type.SEGMENT_END_MANUAL do not contain location data or sensor data.
|
|
|
|
Tracks recorded prior to OpenTracks version 3.15.0, do neither begin with a Type.SEGMENT_START_MANUAL nor end with a Type.SEGMENT_END_MANUAL.
