(How to use T2t: thermal class, source files and output files)
How it Works:
This software searches the track files downloaded from the GPS for ascending areas (thermals). For each thermal T2t creates a waypoint and assigns it a name that contains useful information, such thermal class, wind direction, average climb rate and initial altitude. The source track must be a .PLT (Oziexplorer ver. 3.90.3) or IGC (CompeGPS ver. 4.05) format file. The created waypoints can be saved in a .WPT format file that you can upload to your GPS. You will then carry your GPS with you and use it during your flight, and it will help you to find those thermals again.
You can use the flights from OnLine Contest with T2t: just download the flights made by other pilots in the areas of interest, run T2t against those tracks, load the resulting thermals on your GPS, and you’ll be ready to make their best flights again!
(How to use T2t: thermal class, source files and output files)
Run T2t.exe and fill in the requested information: source file name (.plt/.IGC), output file name (.wpt) that will contain the waypoint list, thermal classes and their names. With some GPS models you can use different symbols (icons) to be displayed (cool!). Click on “Run” button and within few seconds T2t will create the thermal map of the specified flight. Repeat this process with the other available flights.
For a good thermal detection we suggest to use tracks with a sampling interval of 10 secs or less; sampling intervals in excess of 20 seconds will not allow a good thermal map to be created.
Furthermore, please make sure that the source track also contains altitude data, otherwise T2t will not be able to detect the thermals.

An example: can you expect to find good thermals in the area shown above and make a great flight, even if you had never been there before? The answer is YES, FOR SURE!
