New Surveys. New System.
•A series of new, large sky surveys are coming on line, or are imminent:
–Sloan Digital Sky Survey (SDSS) – in the image.
–Panoramic Survey Telescope & Rapid Response System (Pan-STARRS)
–The Large Synoptic Survey Telescope (LSST)
•None of these use the traditional BVRI filters.
•Observatories are not replacing their old UBVRI filter sets.
•Little or no new work is being done to support UBVRI despite its known inadequacies.
