[Proj] wgs point (lat-lon 'NMEA' to N-E 'metric') "was (lat-lon 'degres' to N-E 'metric')"

[Eric Miller]

Lots of people have written interfaces for NMEA compliant devices. 
Unless you're doing it for educational reasons, you might have a look at
the GPS software listed on freegis.org.

There are 60 minutes in a degree and 60 seconds in a minute.  Just like
telling time (more or less).  So,

	4051.1749 N  --> 40 51.1749 N --> 40.852915 N
