@fisholo can you provide us QGIS project and some data to replicate it? Thanks

Environment

g3wsuite/g3w-suite:dev
firefox 112.0.2 (64 bit)
ubuntu 22.04

@fisholo please run g3wsdk.info() within your browser console and update the Environment section with the output of that command.

PS a link to the bugged project would also nice (occasionally, we like to see how others use this software in the real world.. 🗺️😟)

Hi @fisholo , we have verified that the proj4 definition that QGIS server sends to the client is not correct, in order to solve this problem it is sufficient that you insert the correct proj4 definition for EPSG:23032 inside your settings_docker.py if you are deploying via docker otherwise if you are developing inside your local_settings.py like this:

G3W_PROJ4_EPSG = {
  23032:  "+proj=utm +zone=32 +ellps=intl +towgs84=-87,-98,-121,0,0,0,0 +units=m +no_defs +type=crs"
}

I try to create an anonymous user and I give you link of the project!

Many many thanks @wlorenzetti! Works like a charm!
I can create an account for you in order to view the project in production, like @Raruto ask!
I'll send you a private mail with account specifications on an email that you give me.

Thanks a lot!

@wlorenzetti do you think is something that will be fixed by upcoming QGIS server release?

Should we transfer this issue to the g3w-admin/issues?

[wlorenzetti]

NO is a QGIS server issue, we have to speak with QGIS developers.
