How to download elevation map and satellite imagery in the highest resolution?

[onyxlee]

Hi guys, I don't need to create a terrain mesh, I just need to download the elevation map and satellite imagery of the same area, how should I do that? Can BlenderGIS do it, or do I have to use other tools?
Thank you so much.
