Astrometrics
A Stellar cartography lab
aboard a Federation Starship, is employed and serves an important
function to chart regions of space and to determine the ship's
position.
The lab on the Enterprise-D was called "stellar cartography", while
it's "Astrometrics" on Voyager. It can be supposed that both are
synonymous.
