The use of deep learning for world creation

Hello!
I’m currently climbing into the rabbit hole that is machine learning and neural networks, and I though - would it be possible to use a neural network to:
1: Create a landscape from real-world data - mostly not ML, but
2: Paint it with materials based on satellite imagery
3: Add buildings with textures (ESRI city plugin?)

I’d be very interested in hearing your opinion(s) on this idea! I would have a lot of fun making something like that, so I will be happy for any ideas on how to approach it as well.
