i try to achieve a dotted landscape like in this example.
I tried to solve it by an array but i dint get the landscape displacement to work. an easy way would be to add a sphere to each point of a landscape mesh but i don't know how to do this.
Sorry if this is easy to solve, but i am kinda new to blender.
You can do the texture using a brick texture node.
Then use a displacement modifier a highly subdivided plane. For the displacement use a texture that as a height map for your landscape.

Landscape topography from grayscale image
For the glow use a glare node.
You can create one segment with the shape of the light at it center:
Duplicate on X and Y with 2 Array modifiers, create mountains with a Displace modifier:
Give your light an Emission node, give the ground a dark green texture with a Layer Weight to make it glossy:
In Eevee play with the Bloom value to make the lights glow:
