Copernicus Digital Elevation Model datasets

The Copernicus DEM is a Digital Surface Model (DSM) which represents the surface of the Earth including buildings, infrastructure and vegetation. We provide two instances of Copernicus DEM named GLO-30 Public and GLO-90. GLO-90 provides worldwide coverage at 90 meters. GLO-30 Public provides limited worldwide coverage at 30 meters because a small subset of tiles covering specific countries are not yet released to the public by the Copernicus Programme. Note that in both cases ocean areas do not have tiles, there one can assume height values equal to zero. Data is provided as Cloud Optimized GeoTIFFs.

Data processing

Original tiles share one row or column with neighboring tiles, and have sizes such as 3601 by 3601 pixels, 2401 by 2401 pixels, 1801 by 1801 pixels, or something else, depending on the longitude. We removed these shared rows and columns on east and south edges to got the dimensions that are nicely divisible by two, so we could create nice COG overviews. The common properties of COG files are:

Data structure

Each file is its own object in Amazon S3. The data are organised per tiles in original 1x1 degree grid (latest Shapefiles for GLO-30 Public and GLO-90). The basic data format is the following:

Copernicus_DSM_COG_[resolution]_[northing]_[easting]_DEM/

For example, the files for individual tile are available in the following location: s3://copernicus-dem-90m/Copernicus_DSM_COG_30_S90_00_W178_00_DEM/

Metadata

The list of tiles is saved in each bucket as tileList.txt.

Accessing the Copernicus Digital Elevation Model

If you use the AWS Command Line Interface, you can list data in the bucket with the “ls” command:

aws s3 ls s3://copernicus-dem-30m/ and aws s3 ls s3://copernicus-dem-90m/
