I use the term UK Schmidt Survey (or UK Schmidt Southern Sky Survey) for the early work of the UK Schmidt Telescope. The telescope's aim and designed was for Surveys and it spent its time photographing all the sky it could reach, when done with one Filter, repeating with another. The resulting collection of plates is the southern-hemisphere analog to the Palomar Observatory Sky Survey plates, and have been used for subsequent survey efforts, such as the Digitized Sky Survey, and individual lists of various unusual types of objects.
