Scientific paper

We derive a new three dimensional map of H I gas in the Milky Way Galaxy using the latest H I survey data (Hartmann & Burton 1997) and a new rotation curve (Honma & Sofue 1997). The H I disk extends to R ~= 23 kpc and is strongly warped. The 17 kpc ring is most remarkable, and contains ~ 2/3 of the total H I mass, 5.5 × 109 Modot. The 13 kpc ring corresponds to the so-called Outer arm, and the 8 kpc ring to the Sagittarius and Perseus arms. Our map shows an H I deficient ring at R=10 kpc. It coincides with a corotation, if the pattern speed is about 20 km s-1 kpc-1.
