i searched in the image section of google for.....satellite views of mountains, forests, deserts wetlands grassland etc...I would then save the image as and put it in my folders. then i would copy cut and paste in Windows Paint on top of the original drawing that fits the terrain i was trying to create. for example on new planet continent 3 the desert there is part of the Sahara. i can't remember what mountains i used though its a long and tedious process but is worth it in the end
