| Summary:
Cosmological data in the next decade will be characterized by high-precision,
multi-wavelength measurements of thousands of square degrees of the same
patches of sky. By performing multi-survey analyses that harness the correlated
nature of these datasets, we will gain access to new science, and increase the
precision and robustness of science being pursued by each individual survey.
However, effective application of such analyses requires a qualitatively new
level of investment in cross-survey infrastructure, including simulations,
associated modeling, coordination of data sharing, and survey strategy. The
scientific gains from this new level of investment are multiplicative, as the
benefits can be reaped by even present-day instruments, and can be applied to
new instruments as they come online.
