Hello Stefan,
your hint isn't the solution, but might help ;)
1. we are at MapServer <= 7.6, so there is no epsg-file, but the projlib
with the sqlite.db
2. my tests are on debian (with MS 7.6 and 8.0), but the
original-problem has to be solved on a windows machine.
However, I made a test on a debian with MapServer 8.2 and a newer
projlib and there it works. So we will try to update the mapserver to
v8.2 at production.
Thanks!

Hello Jörg,
i couldn't find a hint on what MS version you're using, but with the
first installation of MS8
we also had a projection issue, - same as with you: without any hint in
any log or error file.
In the end it was simply solved by copying the file with the simple name
"epsg" from the
share/proj directory to the /share/proj9 directory (that is configured
through the mapserver_config file).
It's a simple task so maybe you can give it a try, - you need to restart
apache to make
MS aware of the new file.
Good luck

Hi,
I'm having a projection issue. There are two source datasets, one with
epsg 25833 and one with epsg 3068. Both should be at the same place
and they are, when viewing them in QGIS. In mapserver they don't
match. The example works with shp-files, but the problem occurs with
other Formats, eg gpkg, too.
https://schulung.foss.academy/mapbender/application/soldner?#10000@13.33114/52.49205r0@EPSG:3068
I've uploaded everything to
https://files.wheregroup.com/s/2QFHgNBanzJrSrN
When you change the projection to wgs84 or utm33 both polygons match,
with soldner they don't. The pink one with the data source in 3068 is
always displayed correct, but the blue one (data source 25833) is
placed ~400 meters south-west.
epsg 3068:
https://schulung.foss.academy/cgi-bin/mapserv?map=%2Fdata%2Fth%2Fmini.map&REQUEST=GetMap&SERVICE=WMS&VERSION=1.3.0&FORMAT=image%2Fpng&STYLES=%2C&TRANSPARENT=TRUE&LAYERS=mini25833%2Cmini%203068&WIDTH=1323&HEIGHT=1252&CRS=EPSG%3A3068&BBOX=17421.289685579035%2C18846.08290242035%2C19408.843660686984%2C20946.66710358875
AND epsg 25833:
https://schulung.foss.academy/cgi-bin/mapserv?map=%2Fdata%2Fth%2Fmini.map&&REQUEST=GetMap&SERVICE=WMS&VERSION=1.3.0&FORMAT=image%2Fpng&STYLES=%2C&TRANSPARENT=TRUE&LAYERS=mini25833%2Cmini%203068&WIDTH=1486&HEIGHT=958&CRS=EPSG%3A25833&BBOX=385517.0762893588%2C5816411.973997896%2C387875.47100614826%2C5817933.437040822
Thee are no hints in the ms-log and proj-log, below you'll find the
mapfile.
I don't have any more Ideas what's going wrong, perhaps anyone of the
helpful mapserver list can give me a hint?
Regards, Jörg
