Proximity scan
The 24th century display graphic of a proximity scan
A proximity scan is a type of scan used on starships to locate objects near the origin.
In 2151, a proximity scan was among the data displayed on the display table in the situation room next to a planetary surface scan of the tunnel network on Terra Nova. (ENT: "Terra Nova")
In 2153, a proximity scan was activated when Enterprise NX-01 was searching for the Borg-assimilated transport Arctic One. The scan was featured on the display table in the situation room. (ENT: "Regeneration")
In 2369 Commander William T. Riker and Geordi La Forge used the proximity scan aboard a shuttle to detect the Cardassian starships inside the McAllister C-5 Nebula. (TNG: "Chain Of Command, Part II")
