Logistics of civilization with point-to-point superluminal travel calculating a pseudo-current map of the galaxy's navigational hazards
An interstellar civilization has superluminal travel which allows for travel between two points, effectively without traversing the space in between so they don't crash into anything between them and their target.
Navigation presents a problem: the visible stars only give a snapshot of their positions years previous and they have moved since then, so the current position of the target must be calculated.
The dangers of incorrect calculations include getting lost or, less commonly, arriving inside a solid object. Getting lost isn't immediately deadly but costs precious time and fuel to detour, assuming you have the instruments necessary to navigate on your own.
What logistical concerns are involved in the civilization calculating a constantly updating map of the exact position of every star, planet, moon, and other navigational hazard in the galaxy?
(This question is inspired by propulsion in the Battlestar Galactica remake, which uses concepts like "jump drives" and "red lines." I did find an analysis, but wasn't sure whether this applies to FTL in general.)
