           Summary: GPS Sync: not optimal correlation
           Product: kipiplugins
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kde-imaging kde org
        ReportedBy: fabien.ubuntu gmail com


Version:           svn (using KDE KDE 3.5.2)
Installed from:    Ubuntu Packages
OS:                Linux

When parsing a gpx file, gpssync stops at the first match when interval < max gap.

Extract from source code gpsdataparser.cpp:

    for (GPSDataMap::Iterator it = m_GPSDataMap.begin();
         it != m_GPSDataMap.end(); ++it )
    {
        // Here we check a possible accuracy in seconds between the
        // Camera GMT time and the GPS device GMT time.

        int nbSecs = abs(cameraGMTDateTime.secsTo( it.key() ));

        if( nbSecs < maxGapTime )
        {
            gpsData = m_GPSDataMap[it.key()];
            return true;
        }
    }

But, the first match is usually not the best one. gpssync should continue to iterate until it find the best value (min interval)...
