The Herschel infrared Galactic Plane Survey (Hi-GAL) covers the Galactic plane at five wavelengths from 70 to 500 microns. Hi-GAL DR1 is limited to the inner Milky Way in the longitude range +68d > l > -70d and latitude range 1d > b > -1d. The generation of the Hi-GAL photometric catalogs is discussed in detail in Molinari et al. (2016).

The Galactic Plane Infrared Polarization Survey (GPIPS) covers 76 sq. deg. of the first Galactic quadrant midplane, 18<56 deg and -1<+1 deg, in H-band (1.6 micron) linear polarimetry to reveal the plane-of-the-sky orientation of the magnetic field in diffuse and denser atomic and molecular clouds. The Survey consists of 3234 overlapping 10x10 arcmin fields observed using the Mimir instrument on the 1.8 m Perkins telescope.The unique star data file (Clemens et al. 2020) collects all GPIPS photometry and polarimetry and all matching stellar data appropriate to each GPIPS star. The unique star file contains entries for 13,861,329 GPIPS stars.

The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme (KPGT_soliver1) designed to map a set of nested fields totalling 380 sq. deg. Fields range in size from 0.01 to 20 sq. deg., using SPIRE at 250, 350 and 500 microns. These bands cover the peak of the redshifted thermal spectral energy distribution from interstellar dust and thus capture the reprocessed optical and ultraviolet radiation from star formation that has been absorbed by dust, and are critical for forming a complete multiwavelength understanding of galaxy formation and evolution.

The WISE Catalog of Galactic HII Regions consists of 8000 Galactic HII regions and HII region candidates selected by searching for their characteristic mid-infrared (MIR) morphology. WISE has sufficient sensitivity to detect the MIR emission from HII regions located anywhere in the Galactic disk. This is the most complete catalog yet of regions forming massive stars in the Milky Way. Of the ~8000 cataloged sources, ~1500 have measured radio recombination line (RRL) or Halpha emission, and are thus known to be HII regions. This sample improves on previous efforts by resolving HII region complexes into multiple sources and by removing duplicate entries. There are ~2500 candidate HII regions in the catalog that are spatially coincident with radio continuum emission. Previous RRL studies show that ~95% of such targets are HII regions. Approximately 500 of these candidates are also positionally associated with known HII region complexes, so the probability of their being bona fide HII regions is even higher. At the sensitivity limits of existing surveys, ~4000 catalog sources show no radio continuum emission. Distances for ~1500 catalog sources and molecular velocities for ~1500 HII region candidates are taken from the literature.
