<h1>PROJ.org Datumgrid CDN</h1>
<p>
The s3://cdn.proj.org bucket is hosted by the
<a href="https://aws.amazon.com/opendata/public-datasets/">Amazon Public Datasets</a> program, and it
can be accessed via HTTP/S at <a href="https://cdn.proj.org">cdn.proj.org</a>. CDN services are
provided by the AWS Public Dataset team via <a href="https://aws.amazon.com/cloudfront/">CloudFront</a>.
</p>
<p>
The CDN contains <a href="https://www.cogeo.org/">Cloud Optimized GeoTIFF</a> datasets which are mirrored and
managed by the
<a href="https://github.com/OSGeo/proj-datumgrid-geotiff/">https://github.com/OSGeo/proj-datumgrid-geotiff/</a>
GitHub project. Files in the CDN are designed to be used by <a href="https://proj.org">PROJ</a> 7 or later, but any software
project wishing to use the CDN for shifting support are encouraged to participate in the project and leverage the CDN.
</p>
<h2>Mirroring</h2>
<p>If you are able, you are encouraged to mirror the grids via AWS S3 command line: </p>
<pre>aws s3 sync s3://cdn.proj.org .</pre>
<p>If direct S3 access is not possible, you can also use <i>wget</i> to locally mirror
the data: </p>
<pre>wget --mirror https://cdn.proj.org/</pre>
