Universal transverse mercator (UTM)

Dear Dr. Gareth,
thanks alot for your suggestion. I know that there is geotrace, but I am in need of to know the distance between 2 points in meters. Using GPS could not help to find the distance in meters. I think, Kobo can create a feature for transforming from GPS to UTM system and it is very simple for them.

Regards,
