Texture based minimap based on navmesh


I’m planning on making a minimap for my game like diablo 3. It would be cool if you could create a texture based on where you can walk on the navmesh and color that grey with an outline around it, just like diablo 3’s minimap that you can see in the attached image. Now I don’t have any idea if this is possible nor where to start with this.

Any help or links to helpful information would be greatly appreciated!

any ideas?

Thanks in advance!
