useful if you're writing to a target format that isn't the lowest common denominator but the source data

was written for the lowest common denominator. I use this for writing data from geocaching.com to my

Magellan so my waypoints have "real" names instead of the 'GC1234' ones that are optimized for NMEA-

only receivers. A geocacher with a Magellan receiver may thus find commands like this useful.

gpsbabel -s -i geo -f geocaching.loc -o magellan -F /dev/ttyS0

gpsbabel -s -i geo -f geocaching.loc -o magellan -F com1

Suboptions

Many of the available format options in GPSBabel can themselves take options. While we try to make

all the formats do the most sensible thing possible without any extra options; this allows great power and

flexibility in the operation of the program.

Suboptions are comma separated and immediately follow the option itself. The available suboptions are

listed on the individual format pages. We'll make an example from the section called “Google Earth (Key-

hole) Markup Language (kml)”:

gpsbabel -i gpx -f file.gpx -o kml,deficon="file://myicon.png",lines=0

-F one.kml -o kml -F two.kml

This command will read the GPX file file.gpx and create two KML files. one.kml will have the

given icon and no lines between track and routepoints. two.kml will be created with the defaults used

in the KML writer.

Suboptions for the various formats allow you to change serial speeds, pass arguments to filters, change the

type of file written, override icon defaults, and lots of other things. The suboptions for each filetype are

documented on the page in this document that describes the option itself.

Advanced Usage

Argument are processed in the order they appear on the command line and are translated internally into a

pipeline that data flows through when executed. Normally one would:

read from one input

optionally apply filters

write into one output

but GPSBabel is flexible enough to allow more complicated operations such as reading from several files

(potentially of different types), applying a filter, reading more data, then write the merged data to multiple

destinations.

The input file type remains unchanged until a new -i argument is seen. Files are read in the order they

appear. So you could merge three input files into one output file with:

gpsbabel -i geo -f 1.loc -f 2.loc -f 3.loc -o geo -F big.loc

You can merge files of different types:

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 ... 129 130
