  Wide-field imaging from space will reveal a wealth of information about the
globular cluster systems of any galaxies in the local universe that are
observed by such a mission. Individual globular clusters around galaxies in the
local universe have compact sizes that are ideal for the excellent spatial
resolution afforded by space-based imaging, while systems of these globular
clusters have large spatial extent that can only be fully explored by
wide-field imaging. One example of the science return from such a study is the
determination of the major formation epoch(s) of galaxies from the ages of
their globular clusters determined via their optical to near-infrared colors. A
second example is determining the sites of metal-poor globular cluster
formation from their cosmological bias, which constrains the formation of
structures early in the universe.
