G320-330: A comparison along the sector of the Galactic Plane from l=320°-330° of the atomic hydrogen from the SGPS (top; McClure-Griffiths et al. 2005), $^{12}$CO from our Mopra CO survey (middle; Braiding et al. 2015) and $^{12}$CO from the original Dame et al. (2001) survey (bottom). The effect of the improvement in resolution, a factor of ~10 angular and spectral dimensions, is dramatic.
