Excellent program with everything I need all on one screen. Perfect for use on the farm with my iQue, as I can use this for farm related waypoints and not clutter up the address book. Highly recommended.

GPScalc (PalmOS)
GPScalc is a calculator to convert between geodetic longitude and latitude to UTM eastings and northings and to calculate distance and headings between waypoints to within 1 cm accuracy between your GPS position fixes. Read more

GPScalc is an excellent tool for converting coordinates between UTM and GPS. Tested accuracy (using WGS 84) is even better than claimed (within 5 mm), and is good enough for setting reference stations for DGPS. Conversions do take a second or two to run, but the five-star rating is still well deserved for accuracy and support.

Great Program. I have been using it for several years to follow potato crops planting during the cropping season. So I have detailed maps for each farmer and the acreage. Great Job, congratulations.
