I am trying to transform from epsg:4326 (wgs84) to epsg:25832 (utm ETRS89) using Proj.4. I am comparing the results with results from http://valdemar.kms.dk/trf/ .
it seems like the results calculated by proj.4 is off by 2m northing and 4m in easting in Copenhagen. The results farther west are more correct.
Am i missing some sort of correction attributes in my calculation?
