I think I've seen this discussed here before but it doesn't seem to
appear in the archive.
I am using the map package which so far has been fine for my purposes.
Some people I work with have GPS type data that defines positions as
number of metres not degrees. I don't know how much the system
varies, but in New Zealand, they are referred to as Eastings and
Northings.
What I would like to know is how complicated it is to convert between
such data and the normal latitude and longitude that the map package
uses. I assume various datum points are used for different parts of
the world, and knowing the appropriate one and the definition of a
"northing" and an "easting", the conversion would be relatively
straight forward.
TIA
