  A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is
supported by a large representation of the community of Galactic astronomers.
The combination of sensitivity, angular resolution and large field of view make
Roman uniquely able to study the crowded and highly extincted lines of sight in
the Galactic plane. A ~1000 deg2 survey of the bulge and inner Galactic disk
would yield an impressive dataset of ~120 billion sources and map the structure
of our Galaxy. The effort would foster subsequent expansions in numerous
dimensions (spatial, depth, wavelengths, epochs). Importantly, the survey would
benefit from early defintion by the community, namely because the Galactic disk
is a complex environment, and different science goals will require trade offs.
