Garmin vs. magellan gps , looking to buy a handheld GPS, but would like to find out who makes the better system. I will be using it for hunting, hiking, fishing, and traveling in car. Any help would be appreciated.
Either maker’s GPS receiver will work fine. However, do note that Garmin has better American-based customer service. Magellan uses a call center in India, and sometimes their script readers do not understand what you need. But this only comes into play if you have some sort …

Where i can find the formulae for doing conversion calculations for GPS lat-long positions to other coord sys ? latitude longitude coordinates to utm conversions formulae required, to work with.iam using Magellan GPS which sends NMEA strings.i wanna develop the conversion tool.respond if anybody knows.
