Thx for the quick reply Martin, I am willing to contribute a fix/improvement for this issue (while contextually requesting a review from you :-)). I am going to open up a Jira RFE.
Which source of information do you suggest to use as a reference for this projection? I should have somewhere the (in)famous projection reference book from USGS. Do you suggest something better (or easier :-))? Thx a lot, Simone. ------------------------------------------------------- Eng. Simone Giannecchini President /CEO GeoSolutions S.A.S.

I have to admit that I have not cheched the EPSG db yet. The Geotools projection code is derived from Proj.4, and the above-cited page said: "PROJ.4 does not support a latitude of natural origin other than the equator." It may be easy to add this support in Geotools if we know what we are supposed to do with this latitude of origin. Is it just a latitude offset, like "longitude of origin" is a longitude offset? If someone is up for investigating that we could fix.
