Hello Mike,

In the Geographic Tracker, under Options>Set Preferences, there is an "Update Interval" setting.  If you currently have that set higher than one second, you can decrease the interval between updates, and that will effectively speed up the playback.  If it is currently set to one second, that is the fastest it can play back and the only way to get the location to move faster would be to actually remove records from the .gps log file.  This would thin your data, but if it is solely for demo purposes, might be tolerable.  The way to accomplish this, would be to open the .gps log in a text editor, and remove lines that appearing like this (the numeric values will be different for you of course):
$GPGLL,3854.7403,N,07701.27164,W,091053.00,A
Each line starting with $GPGLL is one coordinate point.  Thinning every other $GPGLL record, for example, would make your location on screen move ahead twice as fast at the same update interval.  If you are going to try this, I would suggest making a backup copy of your log file incase you don't like the results.  I hope this helps you, if I may be of any assistance, feel free to contact me directly.

Subject: [MI-L] Simulated Geographic tracker data
  
My boss wants me to do a demonstration of what we are doing with MapInfo & a GPS in the field.  I was thinking that showing simulated GPS data in a familiar area would be somewhat interesting.  After recording some data, I find that it's slow & gets boring quickly.  Has anyone tried (or is it possible) to modify a file to move things along faster in a DEMO?
