I did anyway some time ago was to add my own lookup table as<br>
local/share/proj/hermann in order to gain control over my own<br>
transformations.<br>
<br>
Now I can use: +init=hermann:4314, which resolves to my transformation<br>
parameters (+proj=longlat +ellps=bessel +nadgrids=BETA2007.gsb), whereas<br>
epsg:4314 translates to: +proj=longlat +datum=potsdam +no_defs<br></blockquote><div><br></div><div>Hermann, thank you for the suggestion. I'm doing the same thing (creating my own lookup file) which of course works fine for me, but doesn't help anyone else. I believe that there are about 600 coordinate systems in the Proj4 epsg file that say "HARN" but do actually reference the HARN grid shift files, nor give the user any obvious clues that these grid files are available and could, and should, be used.<br><br></div><div>Thanks,<br></div><div>Rich<br></div><div><br> </div></div>-- <br><div class="gmail_signature"><div dir="ltr">Richard W.
