While the official documentation of datacube-core
is not yet very useful, the project owner CEOS has a much better documentation hidden in another github project named CEOS Data Cube UI
.
The topic I was looking for can be found here.
I will not copy-paste the whole documentation. But the following is the information the prepare script should output to a yaml
file:
