Hi Antti

I am wondering if it is possible to export track (say a section of mountain twisty) from google map to the RC installed on the phone?
I know it make sense to make actual recording of track but sometimes, I just thought it saves a lot of time that I can mark a section of road on google map function and then just export to the phone.

Thanks

    Not really possible, as far as I know. What kind of format does Google Maps save? KML? Never tried to extract routes from it my self :)

    Google Maps exports to KML (click the "View in Google Earth" link above the map). It's an XML data format but doesn't include all the data, just a link to get the data from Google Maps. Inside the KML you download is a link to another KML file that does include all the co-ordinates (lat/long) to create the line on the map. It's usable, although I think the accuracy would make it rather pointless. You could, however, download every speed venue I've found in one shot.

    Maybe these routes could be used to make new tracks. But there is of course a risk that they would be "off" enough to make the track broken ... Sometimes Google satellites / maps are misaligned to the real world.

    Generally, I've seen that they are misaligned. You may or may not be lucky. I've exported quite a bit of my RaceChrono data to KML and you can see how they match up on my website.

    Yep, and that varies country to country. Seems that in USA the alignment is near perfect, but in Australia for example, not really...
