A large-scale three-dimensional model of Galactic extinction is presented based on the Galactic dust distribution model of [CITE]. The extinction AV to any point within the Galactic disk can be quickly deduced using a set of three-dimensional Cartesian grids. Extinctions from the model are compared to empirical extinction measures, including lines-of-sight in and near the Galactic plane using optical and NIR extinction measures; in particular we show how extinction can be derived from NIR color-magnitude diagrams in the Galactic plane to a distance of 8 kiloparsec.
Key words: dust, extinction / ISM: structure / Galaxy: structure
