    Eduardo,

    If you have a NMEA log you can play that back using the GPS->Setup menu. Then while playing it back you can use the GPS->Mark Waypoint from Averaged Position menu command to average a location.

    I would have to see the Novatel log, but most GPS's store a NMEA-0183 log which many applications can use.

    Thanks,

    Eduardo,

    Indeed that is not a NMEA format log. You could load that format with the File->Open Generic ASCII Text File menu command though by specifying 'Point Only' and specifying the appropriate number of fields to skip before the coordinates. That would give you a separate point feature for each line in the file so you could visually see where they are clustered. Does each file represent one recorded set of locations for a single point feature and you'd want to average all of those?

    Thanks,
