Downloading the Copernicus DEMs
In 2021, the Copernicus Program released a high quality global DEM at 30m and 90m resolutions.
It took me a while to track down where to download the actual datasets: they are hosted for free on AWS S3, and can be downloaded with
aws s3 sync s3://copernicus-dem-30m/ --no-sign-request ./copernicus-dem-30m
aws s3 sync s3://copernicus-dem-90m/ --no-sign-request ./copernicus-dem-90m
