Thinking aloud here... assuming that you can render the landscape itself 
without trouble (I assume you can) then using a gradient texture going 
e.g. from black (bottom) to white (top) on the landscape, and rendering 
that with an orthographic camera from above, within a white sphere 
containing a finish {emission 1 diffuse 0}... that would do the job imo. 
Make a large render, at least 2048x2048px.
