    Thanks for your answer. The problem is that I have some hundred TRK files and I would like to convert them all.

    Not sure if your problem is solved but for such operations you can either use gpsbabel or Land with a special Compescript.

    Hello,

    try gpx.tybern.fr/gpxswk.html

    It reads TRK, and can save the track in GPX format.
    It talk only french, but I think you will find easily with icons.

    Last version of GPSbabel no longer read TRK.

    Best regards

    Thanks Bernard for the update on GPSBABEL. Lost track of the changes since I didn't use it for years.

    Thanks for your answers. It looks like the TRK files from TwoNav are not quite standar. The solution tybern is very good, but it cannot place the track on a map, it simply draws it on a white background.

    What I would like is a description of the TRK format used by TwoNav, then I may try to have a python script to translate it to gpx or whatever. I could do it in batch for all my files.

    Best,

    Hello,

    "but it cannot place the track on a map, it simply draws it on a white background."

    Absolutly not !!!

    I suppose you've not selected the right map for the display. May be the selected map is a french one and your track is not, but just select the right map and it will be ok.

    Best regards,

    That's an understatement...

    It is the reason why I decided to read TRK in my application, but not write them !
    I have also some informations about the internal structure if you need them.  

    But if you want to code it yourself, you should know that parsing this format is a pain in the neck because this format is so crappy... There is no grammar, it is not even a language, it was invented and written with the feet...

    Best regards,

    OK, thanks, I don't know if I would try to, but losing all my old tracks it's a pity...

    "OK, thanks, I don't know if I would try to, but losing all my old tracks it's a pity..."

    I wrote my application precisely to no longer be dependent on Twonav tools to use my tracks that I have been storing for more than fifteen years now.

    Yes, your tybern app is great, I start to know it.

    Is there a way to batch transform several tracks at once?

    (je suis espagnol-catalan, je vis à Ceret, on peut parler français)

    Twonav continues to rely on its TRK format, probably to force users to stay within their ecosystem, but it's a double-edged sword, because now it's also a barrier to new users not using an ecosystem that relies on a non-standard data format. For example, the concept of variants only works with TRKs, not GPXs (it would be possible). This is a serious strategic error on the part of Twonav in my opinion.

    Yes. I agree. I moved out of TwoNav for this reason (but Garmin is not much better)

    En français donc ... 😉

    Non, car en fait, c'est une application conçue pour traiter les traces, mais pas formellement un utilitaire de conversion.
    Mais c'est une bonne idée pour les développements à venir !

    Je continue d'utiliser un GPS Twonav, car avec mon application, je peux traiter les TRK et en faire ce que je veux après. Je n'utilise plus Land, ni la version Android de Twonav. Garmin, non, moi aussi, leur ecosystème ne me convient pas.
    Si je devais ne plus utiliser le GPS Twonav (un Cross), certain que désormais, je me tournerai exclusivement vers une application Android (Locus Map est excellent !).

    "Is there a way to batch transform several tracks at once?"

    Notez que vous pouvez importer de nombreuses traces en même temps (par glisser-déposer par exemple), et les exporter ensuite, c'est assez rapide. Vous pouvez aussi les exporter comme "collections", qui permet d'enregistrer un container qui contient plusieurs traces.

    Pour la Catalogne, pensez à aller dans le menu "paramètres", puis "configuration des fonds de carte" : cela vous permettra d'ajouter le fond de carte de l'IGN Espagne dans le menu de choix des cartes si vous en avez besoin.
