Ah sorry moving too quickly (yay coffee). That is indeed a good question, older copies of uDig were using the epsg-h2 jar, I understand epsg-hsql is the preferred choice these days.
uDig also provides a few additional codes (which you can do with a property file and a bit of setup). - https://github.com/uDig/udig-platform/blob/master/plugins/org.locationtech.udig.libs/epsg.properties Still those are all in the "custom" code range and you were looking for 3857 uDig may do a EPSG lookup (you can do a search given a CRS). Some of the EPSG codes are more accurate (contains helpful transforms?) when read from the EPSG database. We have example code for that here: http://docs.geotools.org/stable/userguide/library/referencing/crs.html#matching-a-coordinatereferencesystem Let me know if "matching" helps? -- Jody Garnett On 14 August 2014 at 6:50:40 am, mroguski (mrogu...@megabit.com.pl) wrote: OK, I will try with uploading the definition to postgis. But still I find it strange that udig does that correctly. You wrote that it read my prj file. Yes, but when I read the file everything was OK as well. The question is why udig displayed the data correctly when it read CRS from postgis and my app did not :/ -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Problem-with-reference-systems-transformations-tp5156398p5156415.html Sent from the geotools-gt2-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ _______________________________________________ GeoTools-GT2-Users mailing list GeoTools-GT2-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users
