How to download DEMs before using them?

Hi there,

I want to download different DEMs (SRTM 1sec, COP30m, …) into snaps auxdata directory, manually.
Is there an operator in snappy or gpt to do that for a specific test site (boundarys)?

And maybe a second little question:
Do you have a link, where all the different DEMs are listed and explained?

There is no special operator for downloading the data.
But you could use the AddElevation operator.
When you use it the DEM data for the source product will be downloaded.

In the help you can find some links if you search for dem.
But there is no list which describes all the DEMs.
