Abstract
In the past five years studies of Galactic neutral hydrogen (H i) have undergone a resurgence, led primarily by the International Galactic Plane Survey (IGPS). The IGPS is in the process of imaging the H i throughout the disk of the Milky Way with sensitivity to angular scales between 2 arcminutes and several degrees. Using these data we are revisiting long-standing questions about the large-scale structure of H i in the Galaxy, especially in the often neglected Southern portion. In particular, we trace the H i rotation curve, scale height, and midplane position with much finer sampling than ever before.
