TL;DR: The primary function of the VST and its instrument is to provide surveys in support of VLT science, be it in the form of large homogeneous multi-colour imaging surveys which form the basis for largescale spectroscopic follow-up work, or in its ability to find rare or extreme astronomical objects for further study.
Abstract: In 2004, OmegaCAM will start operations on Paranal as the sole instrument on the 2.6-m VLT Survey Telescope. OmegaCAM is a huge optical CCD imaging camera: its 16k × 16k CCD pixels cover the square degree field of view of the VST almost entirely. The primary function of the VST and its instrument is to provide surveys in support of VLT science, be it in the form of large homogeneous multi-colour imaging surveys which form the basis for largescale spectroscopic follow-up work, or in its ability to find rare or extreme astronomical objects for further study.

TL;DR: In this article, the OmegaCAM 16k x 16k wide field imaging optical camera, which is expected to become operational in 2004 at ESO's VLT Survey telescope (Paranal), is presented.
Abstract: The OmegaCAM consortium, in collaboration with ESO and the ASTRO-WISE consortium, is building a survey system for the OmegaCAM 16k x 16k wide field imaging optical camera, which is expected to become operational in 2004 at ESO’s VLT Survey telescope (Paranal). The camera will be the only instrument on the VST for an anticipated 10 years of operations. It maps one square degree of sky with 0.21 arcsec sized pixels. Both individual programs, including monitoring programs, and large sky survey programs are planned. Here we present the integrated design of the VST-OmegaCAM survey machine, including the hardware (large filters and shutter, cf [4836-34]), the VLT compliant control software (cf [4848-10]) and the strongly procedurized observing and calibration strategies. The strict data taking procedures facilitate pipeline data reduction procedures both for the calibration and the science data. In turn, the strongly procedurized data handling allows European-wide federations of data-products. On-the-fly re-processing of archival data on the request of individual users with their own plugs-ins or newly derived calibrations sets are facilitated in an internationally distributed system. Compared to the classical more static wide-field image archives the newly designed system is characterized by a much more dynamical type of archiving.
