Astrometrics was a specialized lab used for charting stars, planets, nebulae, and other stellar bodies aboard Federation starships. It could also determine the ship's position relative to the galactic core.

One particular example was the astrometrics lab on the USS Voyager, which was designed by Ensign Harry Kim and Seven of Nine. Incorporating Borg technology, it could measure the radiation flux of up to three billion stars simultaneously, resulting in readings ten times more accurate than was previously possible.

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.

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.

The lab became Seven's primary workspace, where she mapped and catalogued interstellar bodies which the ship encountered.

The USS Enterprise-E was equipped with an Astrometrics lab in which a direct link with Starfleet Cartography could be established.
