+ representing recorded flights, and routes representing task
+ declarations in other formats.

+IGC Data Format Notes.
+======================
+Refer to Appendix 1 of http://www.fai.org:81/gliding/gnss/tech_spec_gnss.asp
+for the specification of the IGC data format.
+
+A sample list of software applications that use data in IGC format can be
+found at http://www.fai.org:81/gliding/gnss/gnss_analysis_software.pdf
+
+GPSBabel can be used to translate data in IGC format to and from various other
+formats.
+
+Routes in other formats are used to represent IGC task declarations.
+Tracks in other formats are used to represent IGC recorded flights.
+
+
+
+Converting to IGC format
+========================
+IGC files generated by GPSBabel will NOT pass security validation tests since
+the data they contain cannot be proven to originate from an approved flight
+recorder. For most software applications that use IGC files this is not an
+issue but for competition scoring, record and badge claims the generated files
+will not be accepted as proof of a flight.
+
+A track stored in another format (GPX for example) representing a recorded
+flight can be converted into an IGC file:
+
+ gpsbabel -i gpx -f mytrk.gpx -o igc -F myflight.igc
+
+If multiple track segments are provided in the input file, the one with the
+most points will be used.
+
+A route stored in another format representing a task declaration can be
+converted into an IGC file:
+
+ gpsbabel -i gpx -f myrte.gpx -o igc -F mytask.igc
+
+A route and a track in other formats can be included into a single IGC file:
+
+ gpsbabel -i gpx -f mytrk.gpx -f myrte.gpx -o igc -F myflight.igc
+
+A similar result can be obtained by downloading the track log and routes
+directly from a GPS device connected to a PC. For example to create an IGC
+file from data recorded in a Garmin GPS connected to the first serial port of
+a PC running Linux:
+
+ gpsbabel -t -r -i garmin -f /dev/ttyS0 -o igc -F myflight.igc
+
+For Windows operating systems:
+
+ gpsbabel -t -r -i garmin -f com1 -o igc -F myflight.igc
+
+A waypoint file in another format containing a waypoint whose short name is
+"PILOT" can be merged into an IGC file. The description field of the waypoint
+will be used for the pilot name in the IGC file header:
+
+ gpsbabel -i gpx -f mytrk.gpx -f myrte.gpx -f mywpt.gpx -o igc -F myflight.igc
+ gpsbabel -w -t -r -i garmin -f /dev/ttyS0 -o igc -F myflight.igc
+
+Some formats such as GPX allow routes, tracks and waypoints to exist in the
+same file and can be used to fully populate an IGC file:
+
+ gpsbabel -i gpx -f myall.gpx -o igc -F myflight.igc
+
+
+
+Converting from IGC format
+==========================
+Data in an IGC file can be converted into other formats. For example to
+generate OziExplorer files containing tracks representing the recorded
+flight (myozi.plt) and routes representing declared tasks (myozi.rte):
+
+ gpsbabel -i igc -f myflight.igc -o ozi -F myozi
+
+Or to GPX format:
+
+ gpsbabel -i igc -f myflight.igc -o gpx -F myflight.gpx
+
+Header information from the IGC file will be written to the description field
+of the track(s).
+
+If both pressure altitude and GNSS altitude are recorded in the IGC file, two
+tracks will be written to the new track file, representing the two altitude
+tracks. The latitude, longitude and timestamps in the tracks will be identical.
+
+A route stored in another format can be merged with an existing IGC file that
+has no task declaration, to generate a new IGC file with a task declaration:
+
+ gpsbabel -i igc -f myflight.igc -i gpx -f myrte.gpx -o igc -F mynew.igc
