Issue description

Hello.
Looked at similar questions but couldn't find an answer.
I have a task: I want to display the territory with relief and underground communications, even no idea how to display it all.
If say overhead power lines and poles can be drawn, say in the form of geojason obyektov and the engine will show them, how to be with underground communications, because they will be below the surface, water pipes, sewerage, underground cables, gas. Plus if you add the terrain. I would be grateful for any ideas or ways to combine all this.

And thank you for the library, very convenient and fast
