Abstract

Data from two IR survey cameras UKIRT's WFCAM and ESO's VISTA can arrive at rates approaching 1.4 TB/night for of order 10 years. Handling the rate, and volume of survey data accumulated over time, are both challenges. The UK's VISTA Data Flow System (for WFCAM & VISTA near-IR survey data) removes instrumental artefacts, astrometrically and photometrically calibrates, extracts catalogues, puts the products in a curated archive, facilitates production of user-specified data products, and is designed in the context of the Virtual Observatory. The VDFS design concept is outlined, and experience in handling the first year of WFCAM data described. This work will minimize risk in meeting the more taxing requirements of VISTA, which will be commissioned in 2007. Tools for preparing survey observations with VISTA are outlined.
