Is it possible to create a height map of a completed level?

I figured this out on my own and it turned out I was over-thinking from the start.
There are two ways:

1. Accessing Scene Depth (through Buffer Visualization) and rendering a screen shot from an over-head camera.
2. I created a simple Post Process Material and a corresponding Instance (for fine tuning) and then took a screen from an over-head camera.
