[GRASS-user] The world from space

Hi guys.

Probably an easy task, but I’m having some trouble figuring out how to make a similar result as what can be seen in ArcGIS’ projection “The_World_From_Space”. I’ll need to be able to reproduce that in GRASS in order to keep my project entirely open-source based.

Thanks for your time,

You could try an orthographic projection

Can you describe in more detail what "The_World_From_Space" is like?

Is it like this:

or like this:
