Log2itn

From OpenTom

log2itn is a converter (filter) for NMEA log files. It converts them into .gpx and/or .itn files according to divers parameters. It also shows the summaries about your saved tracks.

log2itn ist ein Konverter für NMEA-logfiles. Er kann dies in .gpx und/oder .itn files umwandeln nach verschiendenen Filterregeln. Ferner zeigt er Zusammenfassungen über die gespeicherten Touren an.

log2itn est un convertisseur de traces pour fichiers .log NMEA. Il peut les convertir en fichiers .gpx et/ou .itn suivant divers paramétrages. Il affiche également les récapitulatifs des tours enregistrés.

log2itn è un programma per convertire e filtrare i file NMEA. Questi possono essere convertiti in .gpx e/o .itn in base ai parametri scelti. Può anche presentare un sommario analitico delle tracce salvate.

log2itn is a conversie-tool/filter voor NMEA log bestanden.

log2itn permits to generate new .itn and .gpx files from the original .log file. Example of use: I make a nice tour. Back at home, I realize that I have set wrong parameters in the TTTracklog-wrapper commandline and i'm not satisfied with my .itn and .gpx files. Using log2itn gives me the possibility to generate new files like I want.

log2itn erlaubt ab die originale .log Datei neue .itn und .gpx Dateien zu generieren. Anwendungsbeispiel: Ich fahre eine schöne Tour. Zu Hause zurück merke ich dass ich die Befehlzeile in der TTTracklog-wrapper falsch parametrisiert habe und meine .itn und .gpx Dateien gefallen mir nicht. Mittels log2itn kann ich dann neue Dateien generieren, und zwar gemäss mein Verlangen.

log2itn permet de générer de nouveaux fichiers .itn et .gpx à partir du fichier .log original. Exemple d'utilisation: Je fais un beau tour. De retour à la maison, je remarque que j'ai mal paramétré la ligne de commande dans le fichier TTTracklog-wrapper et mes fichiers .itn et .gpx ne me conviennent pas. Grâce à log2itn, je peux en générer de nouveaux selon mes envies.

Wishes for next version

• [SOLVED] It would be great to have an option to save in a txt file the stats that appear on the screen at the end of the process (the same that you get from TTTracklog when the -s option is not used). Lapo Mori 10:51, 18 February 2010 (CET)
  • You can do it with: log2itn > output.txt *.log
  • Or edit Log2itn.bat

For Write on file Stat.txt (create) :

log2itn -o log2itn.itn --ii 0 --im 5000 -g log2itn.gpx --gm 91 --gnt --gnd --ih 600 nmea-2009-05-23.log > Stat.txt

For Merge Stat.txt (create or add) :

log2itn -o log2itn.itn --ii 0 --im 5000 -g log2itn.gpx --gm 91 --gnt --gnd --ih 600 nmea-2009-05-23.log >> Stat.txt
