Hi Andreas, some time ago I had a similar problem in the UMN Mapserver. There I could solve it, in which I have supplemented the corresponding epsg entries by a further parameter: “+nadgrids=/usr/local/share/proj/<name of your gsb-File>”. This caused the data to be transformed “on the fly”. Hope this helps.

In Switzerland we need to offer "old" and "new" coordinates (different datums) at the same time with our services and the conversion needs to be done with grid shift files or tin based interpolation. I know that I have to copy the CHENYX06a.gsb file to my proj lib, e.g. /usr/local/shar/proj - but how can I make QGIS Server to actually use this file? I assume that I need to copy an additional config file or SRS/grid shift file combinations to QGIS server and/or specify an environment variable - right? Are there any resources explaining how I can configure QGIS server to make use of these grid shift files? Thank you for any pointers! Andreas
