only 99 waypoints from NMEA file?

[routeconverter]

A possible nice feature is also:
Some way to beautify the route. Means even when using something like SONY GPS CS1 there are many waypoints (every 5 secs one) and some of them are very suspect (mesurement-mistakes,...).

So maybe there is a feature where we can eliminate (via avg-functions,...) this errors?

Yes, push the button with the blue line ("Selects duplicated positions of the position list") and a dialog comes up which allows to

1. Select all duplicate positions within a distance of XXX meters of their predecessor
   
2. Select all position such that at least XXX meters lie inbetween the remaining positions
   
3. Select all positions but every NNN th position
   

After selecting the positions, you may delete (or move) them.

Is that what you where searching for?
