Survey team

A survey team was a specialized group sent to survey a planet on a survey mission, often prior to colonization. They took note of geological and biological oddities. 

In early 2373, Captain Benjamin Sisko led a survey team from Deep Space 9 to the cormaline-rich Gamma Quadrant planet Torga IV. 

Deanna Troi told Zefram Cochrane that the Vulcans who made the First Contact with the Humans in Bozeman, Montana in 2063 were on a survey mission and had no interest in Earth.
