Here we discuss impacts of distance determinations on the Galactic disk traced by relatively young objects. The Galactic disk, ∼ 40 kpc in diameter, is a cross-road of studies on the methods of measuring distances, interstellar extinction, evolution of galaxies, and other subjects of interest in ast...
