    GBT HI and 100 micron emission toward the Spitzer Extragalactic First Look Survey (XFLS) field.

    One of these maps is Galactic HI, the other is 100 micron emission. Can you tell which is which? This paper gives the answer.

    Links to various good galactic HI data.
    This section will eventually contain links to all of the galactic HI data sets of which I am aware, together with information about their suitability for various uses.
