Projection (Groovy Documentation)

geoscript.proj.Projection

A Projection is a cartographic projection or coordinate reference system.

You can create a Projection with an EPSG Code:

 Projection p = new Projection("EPSG:4326")

Or with WKT:

 Projection p = new Projection("""GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]""")
