How RaceRender recognises tracks?

[Valentin]

RaceRender has excellent lap timing system. After reading video file GPS data and pushing "Laps" button on the main screen, opens "Lap List" window. If RaceRender recognises track, there will be list of lap times.If there is no lap list or Start/Finish Point needs slight adjustment, the Start/Finish Point has to be set manually using "Change Start / Finish Point".

If one wants to save these dada for future use, he has to use "Configure Input" button instead. New configuration windows opens, where can be set Start/Finish Point and then Data Profile saved to the *.rrlc file and tihs rrlc file must be handy.

How RaceRender recognises tracs? Is there any way to see list of tracks that are recognised by RaceRender? Or even better, add own descriptions of tracks (it seems that only Start/Finish line coordinates are needed) . It would be quite convenient, then no need for separarte rrlc files.

Small addition to te first post. "Configure input" page above has on left upper corner a blue name of track. Clicking on it starts web browser which sends request to Google Maps using GPS coordinates from first fideo frame. Unfortunately it does not work correctly.

As example, with video, taken on the Kuningam?e track (in english Kuningamae), browser sends request in form

https://google.com/maps/search/58,6530421+25,946411

which ends with answer: " Google Maps can not find request 58,6530421 25,946411". It seems, that there is synax error in requeswt. If we replace decimal separator by dot (instead of komma) and LAT/LON separator by komma (instead of plus) we will have correct request in form

https://google.com/maps/search/58.6530421,25.946411

and Google Maps will open Kunigam?e track's map with separate red mark of my kart position next to the track.

However, it seems, that this syntax error has to be handled separately and is not connected with recognising or not recognising tracks. Kuningam?e and Rapla tracks have both the same syntax error in request, but Kuningam?e track is recognised but Rapla track not.

Finally I have impression, that RaceRender has just list of track names with their Start/Finish line coordinates. If coordinates from video are close enough to these data, the track is recognised. In this case the question is, if and how these data can be edited by user.
