"This needs more testing.  There might be a loss of accuracy in some cases but I think you can control it by choosing a suitably small additive constant. Chris"

Firstly,Thanks for all your work on gHowl... really great tools!I am looking for advice on how to approach the GPS data that I am getting out of a GPS logger.  The format is currently GPRMC and I would like to be able remap this into xyz.It seems as though I need to convert my GPRMC into WSG84... which would then allow me to use the Geo to XYZ component. You can see below that I have tried unsuccessfully to use the Format Geo component with the raw GPRMC file (that would be too easy)  and then…See More
