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
