One particular example is the astrometrics lab on the USS Voyager, which was designed by Ensign Harry Kim and Seven of Nine. Astrometrics was used for charting stars, planets, nebulae, and other stellar bodies. It contained a large wraparound holographic wall screen which could display a stellar region three dimensionally. There were a series of control panels to manipulate the screen. The area below the screen and in front of the control panels could be used as a stage during presentations. Astrometrics also included three workstations on the side wall. Seven spent many hours in the lab mapping and cataloging interstellar bodies which the ship encountered.
For convenience or advanced analysis, astrometrics could also be used for communications purposes or even as a workplace for easy access to sensor information. Astrometrics was used by the crew of Voyager to communicate with Earth once contact was established through the Pathfinder Project.
Harry Kim and Seven of Nine updated Voyager's astrometrics lab at the request of Commander Chakotay in 2374. According to Chakotay, the lab had not been updated since Voyager left spacedock. (VOY episode: "Revulsion")
In 2375 when Seven suffered a type of multiple personality disorder, she took on the persona of Ferengi DaiMon Torrot and offered Captain Janeway twenty bars of latinum for the large astrometrics screen. (VOY episode: "Infinite Regress")
The USS Enterprise-E has an astrometrics lab in which a direct link with Starfleet Cartography could be established. Interference from nearby astronomical phenomena (such as the Bassen Rift) could interfere with the lab's link with Starfleet Cartography. Lieutenant Commander Data used the lab to plot the Enterprise's rendezvous with Star Fleet Battle Group Omega in 2379. (TNG movie: Star Trek Nemesis)
