This format can...
read and write tracks
This format is derived from the xcsv format, so it has all of the same options as that format.
With this format we support Sportsim trackfiles located in zipped .ssz archives.
Currently we cannot read zipped files directly with GPSBabel. So you have to extract the archive before you can use any file. The trackfiles have .txt extensions.
Sportsim provide software applications and web-based graphically simulated performance information and image solutions to outdoor active people.
