Re: [udig-users] WGS84 problem

While scaling a projected system might be useful, I don't think that
it makes much (physical) sense to scale a geographic coordinate
system.
So I assume there is no way to scale the WGS84 system (but I might be
wrong) from the projection definition.

Perhaps through the new sld functions that geotools added lately? But
I would not know how. Jody?

Ciao,
Andrea
