 #### Surface subdivision and refinement
 Usually when surface or elevation models are imported in Blender they are downsampled to a defaults subdivision resulting in smoothing out the surface details. The following procedure subdivides the imported mesh into smaller faces to enhance the surface representation.

 ### V. Shading the scene
-Now we will create a mixed material to combine Orthophoto and viewshed maps. We will use emission shaders to show viewsheds as glowing surfaces. For doing that we have created grayscale viewshed maps with black background, emmission shader assigns greater light emmission power to the lighter pixels.
