Face-on view of the Milky Way spiral arm structure following the Reid et al. (2014) model. We show the Norma (cyan), Scutum-Centaurus (green), Sagittarius-Carina (red), Local (yellow), and Perseus (Gray) spiral arms. The width of the spiral arms shows the width estimated by Reid et al. (2014). The circled GC represents the Galactic Center and ⊙ represents the Sun. The black lines represent the GMF samples of this work (at negative X values) and R14 (at positive X values). The red lines show the filament sample from Wang et al. (2015), based on Herchel emission data. The green line shows Nessie (Jackson et al. 2010; Goodman et al. 2014). The blue lines represent other previously known filaments (Beuther et al. 2011; Battersby & Bally 2014; Li et al. 2013).
