How to import high quality google/bing maps satellite imagery for an overlay

Hello, I would like to use a satellite imagery, maybe by using API for an overlay because I want to do real life roads,. This means I need a very good quality overlay, but i haven’t found anything. I hope someone can help me.
Thanks

You can’t, for a 1001 reasons thats not even worth explaining for the billionth time.

Use a road atlas and a GIS program like everyone else.
Openstreet is generally accurate.
Certainly good enough to extract spline data to utilize on the level regardless of the texturing…
