<p>We could have a OSRSetAutoclosePROJDatabase() global function

creates the per-thread PROJ context<br>

<p>An alternative would be to enhance PROJ to have a mode where the
SQLite3 db handle would be shared amongst several contexts. In
theory that could be possible as you can invoke sqlite3_open_v2()
with SQLITE_OPEN_FULLMUTEX. But would require non completely
trivial changes.</p></div></blockquote><div>Thanks. I can work around this issue for now.</div><div><br></div><div>Changes in GDAL might be nice, but I need to work with what's available today. I could certainly PR the first suggestion if there is interest. Perhaps I'm at the point where I should be using PROJ directly rather than as wrapped by GDAL.<br></div></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature">Andrew Bell<br><a href="mailto:andrew.bell.ia@gmail.com" target="_blank">andrew.bell.ia@gmail.com</a></div></div>
