We construct revised near-infrared absolute magnitude calibrations for 126 Galactic Wolf-Rayet (WR) stars at known distances, based in part upon recent large scale spectroscopic surveys. Application to 246 WR stars located in the field, permits us to map their galactic distribution. As anticipated, WR stars generally lie in the thin disk (~40pc half width at half maximum) between galactocentric radii 3.5-10kpc, in accordance with other star formation tracers. We highlight 12 WR stars located at…
