The 2mass Tully–Fisher Survey (2mtf) aims to measure Tully–Fisher (TF) distances for all bright, inclined spirals in the 2mass Redshift Survey (2mrs) using high-quality Hi widths and 2mass photometry. Compared with previous peculiar-velocity surveys, the 2mtf survey provides more accurate width measurements and more uniform sky coverage, combining observations with the Green Bank, Arecibo, and Parkes telescopes. With this new redshift-independent distance database, we will significantly improve our understanding of the mass distribution in the local Universe.
