<p>Hi Sean,</p>
<p>This is actually documented at
<a class="moz-txt-link-freetext" href="https://proj.org/en/9.4/specifications/geodetictiffgrids.html">https://proj.org/en/9.4/specifications/geodetictiffgrids.html</a>:
"Files hosted on the CDN will use <a class="reference external"
href="https://www.awaresystems.be/imaging/tiff/tifftags/compression.html">Compression</a>
= DEFLATE
or LZW" . I've also just verified that the reality matches the
documented statement. We only use DEFLATE.</p>
<p>Even<br>

<div>Hi all,</div>
<div><br>
</div>
<div>I'm building some fiona and rasterio binary packages. They
include PROJ, and TIFF to get the PROJ grids. On Windows, I'm
relying on vcpkg for everything, and currently the liblzma
port is broken. If I patch vcpkg to disable liblzma, will my
builds be able to access data in the CDN grids?</div>
<div><br>
</div>
<div>Thanks,<br>
