  Policy Brief on "Latest Developments and Opportunities in Sky Survey",
distilled from the corresponding panel that was part of the discussions during
S20 Policy Webinar on Astroinformatics for Sustainable Development held on 6-7
July 2023.
  Sky surveys have been a crucial tool in advancing our understanding of the
Universe. The last few decades have seen an explosion in the number and scope
of sky surveys, both ground-based and space-based. This growth has led to a
wealth of data that has enabled us to make significant advances in many areas
of astronomy, and help understand the physics of the universe. They have helped
us discover new astronomical objects, the origin of the elements, dark matter
and dark energy, the accelerated expansion of the universe, and gravitational
waves. They have helped us study the distribution of neutral and ionized matter
in the Universe and test our theories about the origin and evolution of
galaxies, stars, and planets. We explore recent advances and potential avenues
in sky surveys, and examine how these developments may impact the field of
international astronomical research.
  The policy webinar took place during the G20 presidency in India (2023). A
