We present preliminary maps of the 3-D spatial distribution of cold (T <1000K) neutral and warm (T 5000K) partially ionized interstellar gas as traced by the NaI and CaII absorption lines observed towards stars with distances < 500pc from the Sun. These maps have been constructed from high-resolution (R 80,000) spectral data collected towards 1600 sight-lines, with the 3-D local gas density distribution being calculated from an inversion of the derived column density values. Our new maps, which trace the gas density within a 1kpc 3-D data cube surrounding the Sun, clearly show the neutral boundaries to several interstellar cavities that surround our own Local Bubble region (e.g. Loop I) and also reveal several adjacent interstellar tunnels and chimneys. Our final goal is to obtain maps based on 2000 interstellar sight-line measurements, and these data will be a valuable tool in solving several anomalies linked to the distribution of local gas such as the puzzling distribution of D-to-H values as measured within 1kpc by
the NASA FUSE satellite.
