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.<o:p></o:p></span></p>

<p><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Hi,<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">I have to configure QGIS server to properly handle grid shift files. 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.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">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?<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Are there any resources explaining how I can configure QGIS server to make use of these grid shift files?<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Thank you for any pointers!<o:p></o:p></span></p>
