Hera are awk and exe filters that produced the CSV and KML files from the NMEA log. I know the GPS Logger has the option to write the KML data lines directly, but the KML filter might be handy for someone who wants the best of *both* worlds: full NMEA detail *AND* Google Earth plotting, too. (Besides, my program adds the file preface to make a ready-to-use KML file in one step!)

The .exe files are just compiled versions of the .awk files; usage depends whether the user has an awk processor or not:
C:\>awk -f NMEA2KML.awk GPS123.TXT > GPS123.KML
Or:
C:\>NMEA2KML GPS123.TXT > GPS123.KML
(assuming NMEA2KML is in your path or in your current directory). Likewise for NMEA2CSV.awk and NMEA2CSV.exe, to make Excel-ready files of location, altitude (in feet) and speed (in MPH) for the Chart Wizard.

These awk and exe files may be shared freely.
