I may have another answer to your question (since the X and Y co-ordinates were just swapped). Here are the docs: * http://docs.geotools.org/latest/userguide/library/referencing/order.html TLDR: Scientists and Sailors measure location lat/lon order based on more accurate measurement first. Compu

OK I found a workaround for the problem. I wrote a simple method that projects the data from the CRS they are really in, into the CRS defined by the EPSG code. Here it is: public void reproject(DataStore dataStore, String sourceName, CoordinateReferenceSystem currentCRS, CoordinateReferenceSyste

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:/

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 m

When possible load your data into postgis with the correct SRID, you can look them up on line here: http://epsg.io or http://spatialreference.org You can teach both postgis, geotools and geoserver about additional codes (in case your local government has made something up that is not official).
