The more important thing for such travel is having the technology to travel to these worm holes, rather than just locate them on a map.
Since the ancient civilization was able to reach these wormholes, we must assume one of the two
1. They had efficient space travel technology
If even their technology was good, ours would have become incredibly better and we would know and be able to reach many more wormholes than them. Their work would only have historical importance. This is the most likely case if i am to take your words literally (and now humanity is able to reach anywhere in the universe thanks to those maps.)
If they were a civilization apart from us, then we would not be able to access, or even predict where they would be now. Wormholes and expansion of the universe are still only theories, so we cannot exactly calculate their positions as of today. Even if we knew the rate of expansion of the universe down to a single kilometer, there a number of other factors, such as gravity of near by bodies, mass sucked by wormhole ever since, velocity at which one is pulled in, etc. which we have no idea whatsoever of.
2. The wormhole entrances were located on the earth
There is a minute chance they are still here (if 'expansion of the universe' is a false theory) but I wouldn't think so. If they are, good for us because
(a) we can use the wormholes
(b) we have good proof for proving Big Bang false, and researching into new theories.
