[Geotools-gt2-users] How to transform between different coordinate systems

[Malm P. <pau...@sa...>]

Hi list!
I'm trying to setup a projected coordinate reference system:
The variables I have, read from the raster file header is:

Projection=Mercator
Geodetic Datum = NAD83
Standard parallel = 58.0

I don't know anything about the ellipsoid.

Is it possible to find the EPSG codes for the projection and datum and then create a projectedCRC from those, or how do I do this?
The variables could could be other datums, projections etc.

Kind regards,
Paul
