Do users entering coordinates need to know?
No.
I'm not up on all this geo stuff, so stop me if I'm being stupid. Though pointers to places where I can get this knowledge would be appreciated. 3D spatial reasoning is always the bit I don't do well on in IQ tests, so this stuff doesn't come easily for me.
Doesn't the ellipsoid used have an effect on the Lat/Long? Doesn't this mean we need to specify which one is expected? In other words, does a single point on the globe have a different Lat/Long depending on the ellipsoid in use?
From my brief reading of the README for Geo::Coordinates::UTM, this seems to be the purpose of the module.
