I need to convert a lot of garmin GDB files to GPX in order to convert it to another vector format. Is there any tools available can do a batch convert from garmin GDB files to GPX? Using MapSource allow only one file at a time.

You may use GPSBabel.

garmin GDB format is supported (see this page). Something like that should work:

gpsbabel -i gdb -f file.gdb -o gpx

A short batch file to loop through and convert all files in a directory:

for %%f in (x:\garmin_data\*.gdb) do (
   gpsbabel -i gdb -f "%%f" -o gpx -F "x:\gpx_data\%%~nf.gpx"
   )

The first -f is the input file and the second is the output. See here about the %%~ syntax.

  • Thank you, I tried and it's a good app, unfortunately the output is in one single file, I'm hoping each gdb get converted to each gpx. – Zery Jan 4 '12 at 15:40

    @Zery - Sounds like you need to loop through your files one by one and call gpsbabel on each one as you go. – Chad Cooper Jan 9 '12 at 16:19
  • @Chad - thank you, why don't I think of that, in fact I can even do it from inside my MapInfo using MapBasic and then just look for another source how to convert gpx to mapinfo tab programatically. Thank you. – Zery Jan 9 '12 at 23:43

    I added an example batch file to loop through files in a directory – matt wilkie Feb 22 '12 at 17:51
