If you have a map of named pulsars you could define a coordinate system that would uniquely define a point by using the distances to the closest four pulsars.example Larry 5.0, Curly 11.5, Moe 222.4, Shemp 502.3. Let the computer do the math and knowing where the pulsars are in absolute galactic terms.
This would be locally useful and spare the user from a distant origin point and spare the author and reader lots of angle measurements.
And since it's unlikely the pulsars are going to be well defined it makes proving continuity errors difficult (like why Star Trek avoided real stars - some trekkie could map the Enterprise following a very random voyage.)
The Voyager 1 probe for example used a very redundant 14 Pulsar map to point to Earth.
