  The next decade will feature a growing number of massive ground-based
photometric, spectroscopic, and time-domain surveys, including those produced
by DECam, DESI, and LSST. The NOAO Data Lab was launched in 2017 to enable
efficient exploration and analysis of large surveys, with particular focus on
the petabyte-scale holdings of the NOAO Archive and their associated catalogs.
The Data Lab mission and future development align well with two of the NSF's
Big Ideas, namely Harnessing Data for 21st Century Science and Engineering and
as part of a network to contribute to Windows on the Universe: The Era of
Multi-messenger Astrophysics. Along with other Science Platforms, the Data Lab
will play a key role in scientific discoveries from surveys in the next decade,
and will be crucial to maintaining a level playing field as datasets grow in
size and complexity.
