I see that the danish system is "UTM Zone33 Euref89", 8, 115, 7, 15.0, 0, 0.9996 , 500000, 0 in the prj file, i know that the 115 is the datum (because lars say it me) but and the other parameters?? I would have paste one new row in the prj file with "CRS - ETRS-UTM30", 8, 115, ?, ?, ?, ? , ?, ? and later how i will can refer to this proyection??
or i can put in the mapbasic window: Set CoordSys Earth Projection 8, 115 ,"m",?,?,?, ?, ?, ? someone can solve the interrogations please? for the 30 zone it would be: set map CoordSys Earth Projection 8, 115, "m" , -3, 0, 0.9996, 500000, 0 ???

Esteban Rodr�guez CC: Mapinfo-L Asunto: Re: MI-L proyection CRS - ETRS-TMzn Off course you can, you may just have to define them yourself in the MAPINFOW.PRJ file. The ETRS89 datum is 115, and the rest is just as normal UTM. Datum 115 was defined in MapInfo Pro 6.0 "Danish Projections" includes its two relevant ETRS89 projections.
