north/south)
I thought it was the other way around?
arrrgh, you're right. LONGITUDE is east/west, LATITUDE Is
north/south. so, its X = long, Y = lat.
doy!
Yea, it is one of those inverse things, longitudinal lines run in a N-S
direction but are plotted in the E-W direction and vice versa for
latitude. Me remembering usually involves a certain amount of hand
waving while I work it out on an imaginary globe:)
