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:)
