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.

cop-dem's Issues

AWS OpenData Branch

Is your feature request related to a problem? Please describe.
Create a new branch to use AWS OpenData as the source, and hold any customization required for the AWS variant.

Describe the solution you'd like
Make a branch on this repo, and review the package for any places where customization might be required for a new host.

Add Collection Generator

Is your feature request related to a problem? Please describe.
Current code only generates items, does not generate a Collection STAC json.

Describe the solution you'd like
A a second command to generate the Collection template than can be easily amended based on final host of the data. Should have a flag for glo30 vs glo90.

Describe alternatives you've considered
Not adding to the codebase

Alternate HOST options

Is your feature request related to a problem? Please describe.
Make it easier to specify a different HOST provider.

Describe the solution you'd like
CLI option to switch between host options, leaving the other Provider values constant.

Describe alternatives you've considered
There was no good way to amend the existing Provider with an additional tag, so a HOST is written even if it's the same as a Processor.
