PROJ.org Datumgrid CDN

The s3://cdn.proj.org bucket is hosted by the Amazon Public Datasets program, and it can be accessed via HTTP/S at cdn.proj.org. CDN services are provided by the AWS Public Dataset team via CloudFront.

The CDN contains Cloud Optimized GeoTIFF datasets which are mirrored and managed by the https://github.com/OSGeo/PROJ-data/ GitHub project. Files in the CDN are designed to be used by PROJ 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.

Mirroring

If you are able, you are encouraged to mirror the grids via AWS S3 command line:

aws s3 sync s3://cdn.proj.org .

If direct S3 access is not possible, you can also use wget to locally mirror the data:

wget --mirror https://cdn.proj.org/
