ABSTRACT:
 
2D emission-based maps have been used for decades to estimate the reddening and emission
from interstellar dust, with applications from CMB foregrounds to surveys of large-scale
structure. For studies within the Milky Way, however, the third dimension is required.
 
I will present our work on a 3D dust map based on Pan-STARRS1 and 2MASS over 3/4 of the sky,
http://arxiv.org/abs/1507.01005), assess its usefulness relative to other dust maps, and discuss future work.
