Yes. The WBT log contains the timestamp, latitude and longitude for =20
each point and in later versions the altitude is in there too. The =20
speed and heading can be calculated from that data.
The original version I committed calculated the speed but I think =20
Robert pointed out that that was inconsistent with other input =20
