Here is another way to visualize your flight.

1) Reformat your IGC tracklog using GPSDump to the KML format (Ctrl+O and then
Ctrl+S)

2) Register here: http://flightlog.org/fl.html?l=1

3) After you receive a password via email login here:
http://flightlog.org/fl.html?l=1&a=37

4) Click New flight and then on the next page click "Click Here"

5) There are four fields with red astricks indicating that they need to be
filled out. I only did the first three, seemed to work.

6) In the Tracklog field click Browse and  select your track log in kml
format.

7) When the flight description page comes up click
PARALOGG.SE -
paragliding tracklog analysis.

8) Under the map click "Analysis."
