Hi Andrea,
Thanks for the quick response, I managed to solve the issue by defining the
correct projection parameters in the epsg_operations.properties file.
Cheers,
Attila

Hi,
I have been struggling with this problem for quite a some time now.
In a nutshell:
1. I have defined a custom ED50 UTM 31N (EPSG:23031) projection in the
epsg_overrides.properties file (replaced the original TOWGS84 parameter set
with TOWGS84[-89.5, -93.8, -123.1, 0.0, 0.0, -0.156, 1.2]).
2. If I check the TOWGS84 parameter using the SRS list or the Reprojection
console it shows the correct numbers.
3. However, testing the parameters using the Reprojection console keeps
failing. The ‘Show transformation details’ window shows the ‘original’
parameters (PARAMETER["dx", -116.641], PARAMETER["dy", -56.931],
PARAMETER["dz", -110.559], PARAMETER["ex", 0.893], PARAMETER["ey", 0.921],
PARAMETER["ez", -0.917], PARAMETER["ppm", -3.5200000000346066]) and not the
ones I have defined in the epsg_overrides.properties.
Not sure why it's not working. You might want to try providing custom transform
params instead using epsg_operations.properties:
