I think that this has been discussed in various ways before, but had some time on a windy day and have created a basic utility to take the GPGGA sentences from .trk files and convert them into .kml files that can be opened with Google Earth.
You just need a PC with PERL installed which is standard on a MAC and downloadable for free to a Windows PC. No mobile or tablet support.
Any suggestions or comments would be appreciated.
