Hi,
I have noticed that tracks seem to consist of a series of straight lines and not a curve, each section being perhaps 50 yards or so.
Looking at Overlay, List, Tracks, Edit. I see that there are 2 options. Update Time whcich is set to 10 secs, and Update dist which is set to 15 m.
Is it possible to change the default setting?
If so will it make the tracks follow a curve more exactly?
Thanks
Leigh

This is really a question about memory space on your storage card. I believe that the way a track is recorded is that if either of these limits are met then it will record a trackpoint. Therefore to get the smoothest track you need to set it to 1 metre and 1 second. You will also need to increase the number of trackpoints in the log.

More realistic values will depend on your actual usage model. For instance the 10M/10s is probably OK for walking, but for driving would not give you such a smooth track.

At the end of the day it is a trade off between memory and accuracy of recorded data.

BTW dont forget to exit the application when you have finished. MM does not write the data to the store card properly until you do. If you have to soft-boot for any reason and you havent exited (or MM crashes) then you will lose all the marks and tracks from the session.
