Decoding Proprietary Marine Track Files

This package contains tools for decoding Raymarine's ARCHIVE.FSH files, as well as Garmin's IMG archives and the TRK subfiles.

Parsefsh

Parsefsh is a tool to convert Raymarine's ARCHIVE.FSH files to OSM, GPX, or CSV format. It is written in portable manner and should compile and run on most systems as long as they are based on a Little Endian CPU (such as Intel). It is written on Linux but tested also on FreeBSD and Windows.

Parsefsh reads FSH data from standard input (stdin) and outputs the waypoints, tracks and routes in OSM, GPX, or CSV format to standard output (stdout). Use the command line option -f gpx or -f csv to changes the output format to GPX or CSV. OSM is the default format. The following command shows how to run it.

parsefsh < ARCHIVE.FSH > archive.osm

Splitimg

Splitimg is a tool which splits Garmin's IMG and ADM files into its subfiles. IMG/ADM files are actually archives containing a set of other files called subfiles. Using the appropriate converters, those subfiles may be further processed, e.g. the tool Parsetrk parses TRK subfiles which contain tracks recorded by marine chart plotters of Garmin.

Splitimg reads the IMG/ADM file from the standard input and creates the subfiles in the current working directory or in the directory given by option -d. To run Splitimg simply type the following command:

splitimg < GMAPSUPP.IMG

Parsetrk

Parsetrk is a tool to convert Garmin's TRK Subfiles files to OSM, or CSV format. It is written in portable manner and should compile and run on most systems as long as they are based on a Little Endian CPU (such as Intel). It is written on Linux and currently only tested on Linux.

Parsetrk reads TRK data from standard input and outputs the tracks in OSM, or CSV format to stdout. Use the command line option -f csv to change the output format to CSV. OSM is the default format. The following command shows how to run it.

parsetrk < USERDATA.TRK > track.osm

Note

Please note that TRK files usually do not exist as standalone files. The Garmin chartplotters store the tracks in ADM files which are archives for a set of subfiles. Thus, the ADM file has to be split into separate files (such as USERDATA.TRK) before Parsetrk can be used. To split ADM files you may use the tool Splitimg. See there for further information.
