OK, I ask it differently: for what purposes the database (no matter whether Access, Postgres, HSQL or what ever) is required?
I'll ask, because I don't have any experience with databases and I don't see a reason filling a database with a 6MB sql script for a plain transformation. -- Mike [EMAIL PROTECTED] schrieb: > Hi Mike, > > Sorry, I think you where talking of MS Access or Postgres. > > The HSQL database is inside the jar file, so you don´t have to install any > kind of server etc. > > You can use also WKT of course. > > ------------------------------------ > > CRSFactory wktFac=FactoryFinder.getCRSFactory(null); > > wktFac.createFromWKT(wkt); > > ------------------------------------ > > To get the WKT for the coordinate systems you can use the HSQL database once. > If you want to make a transformation to Gauß-Krüger the parameters in the > "gt2-epsg-wkt-2.2.2.jar" aren´t sufficient. > > > Michael > > > -----Ursprüngliche Nachricht----- > Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Mike Lehmann > Gesendet: Montag, 19.
