<p class="MsoNormal"><span lang="EN-US">I got 2 Questions.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">First question:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is it possible to add a 2D Helmert transformation to the proj.db database. I tried adding it to the helmert_transformation_table, but proj.db didn’t let me choose a projected crs as source transformation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I want to add a helmert transformation which uses ETRS89/GK25 as source crs and transforms it into the finnish VVJ crs.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">My second question is: <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I tried adding the helmert transformation as a proj string to the other_transformation table, but proj won’t use it. I also added an entry into the usage table for the transformation.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When I add a normal helmert transformation or a grid transformation, proj has no problem using them after they are added, but not when I add a transformation in other_transformation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks for your help.<o:p></o:p></span></p>
