[Mapserver-users] RE: latitude and longitude

[Ed McNierney]

Håvard -

What exactly do you mean?  Do Norwegians like maps where East is up at the top?  Or are you talking about projected coordinate systems, rather than latitude and longitude?

In Europe (in Norway, anyway) the tradition is to use x for
north and y for east.
I don't like it, but it is difficult to convince the surveying
and geodesy people to change to the more intuitive(?) x for
east and y for north.

There's no reason you couldn't turn the Earth so the equator was a vertical line up the middle of your map, but people just don't seem to do it that way.
