How do you create a "pictureMap"?

[A140 13]

Hello,

 

I've been recently attempting to create a "pictureMap" for my terrain, however I don't know how to go on about it.

I want to generate one that looks a bit realistic like the "pictureMap" for Stratis at; "A3\map_Stratis\data\pictureMap_ca.paa"

I can cope with it being not-as-realistic but I don't even know where to start.

 

Thanks.

Just use your sat map and a blue gradient (for water) behind your land mass.
