Earlier this year I scored a paragliding where we checked pilots heights and applied a warning or penalty for breach's. This can be easily done with CompeGPS. Load your first tracklog, right click on it and select 'colour track by...' and 'GPS height'. Then right click on the GPS Altitude display area and 'Select range for this value'.

We used the height at which a warning was issued for the minimum value and the height at which a penalty was applied for the maximum value. After doing this, tracklogs that were OK would be blue, those which required a warning had some light blue/green/yellow and those that needed a penalty contained red. If you set both values the same you will get a tracklog that is green where the height is exceeded and yellow when it is not exceeded.

We also had the airspace loaded (an OpenAir text file that CompeGPS loads as a map) so we could see where pilots were when they got to high. All this was used to enforce the CIVL rules regarding airspace infringements.

SeeYou also lets you see airspace violations in this manner.
