To add surface to the blank template is very, very easy. First you need a noise. The most versatile and common noise type is Perlin fractal. The frequency makes the noise more scattered and smaller. The strength makes the noise stronger or weaker, aka bigger or smaller. The octaves make it detailed. High octaves makes it very detail, while low octaves is vice versa. You need to use a generate height or basic arithmetic (set it to A*C) to make the terrain, and put an update height under the two to actually generate the terrain. Hope this helps!
