The new survey will cover longitudes of 15 < l < 65, -15 > l > -95, with a latitude width of 2.5 degrees; 55% of the survey will overlap with GLIMPSE, and 45% will cover new territory. The survey strategy of 3 HDR visits on each sky position will increase the dynamic range over GLIMPSE by a factor of 13 on the faint end and 3 on the bright end. The survey will be enhanced by several complementary surveys at near-IR, mid-IR, far-IR, submm, and radio wavelengths. Deep GLIMPSE will allow us to map stellar Galactic structure out to the edge of the stellar disk; map star formation and H II regions in the far outer Galaxy; improve our estimate of the star formation rate (SFR) of the Galaxy and study the SFR as a function of Galactocentric distance; study low-mass as well as high-mass star formation in the Galactic plane and determine stellar mass functions and evolutionary timescales of YSOs as a function of stellar mass and environment; continue to catalog PAH bubbles, IRDCs, YSO outflows, stellar clusters, external galaxies, brown dwarfs, and more; and search for dwarf galaxies hidden by the Galactic midplane.
