About FAI/IGC Flight Recorder Data (.igc)

IGC is the plain-text flight log written by gliding and paragliding flight recorders — one line per record, with GPS position and an altitude trace from GPS, a barometric sensor, or both. Written by FAI-approved flight recorders and flight-computer apps such as XCSoar, and read by contest platforms like WeGlide and XContest; a file converted by RouteConverter cannot pass the security check required for official badge, record or competition claims.

About KML (.kml)

KML (Keyhole Markup Language) is an XML format for placemarks, paths and polygons, built for map visualization rather than device navigation. It's native to Google Earth and Google Maps' "My Maps", and read by most desktop GIS tools.
