How can the entire universe be mapped?

Inspired by Mapping the far side of the galaxy, I wondered how it would be possible to create a real-time map of the entire universe. As that question dealt with the issue of a one-time travel to the other side of the galaxy and figuring out where you are based on existing mapping data, this question focuses more on how to make a total map of the universe with all the resources you could ask for.

Let's make some assumptions:

• A civilization has the means to travel to any point in the universe in an instant
• Said civilization has enormous resources (due to aforementioned zero-time travel) to place a tracking beacon by every star, planet, moon, and asteroid in the universe.

So here comes the issue: how can the universe be accurately mapped when the stars in the night sky look different from every solar system?

Perhaps more importantly, how could any given section of space-time be considered "correct" if a planet looks like a primordial puddle from one section of space-time and a thriving trade hub from another?
