These maps of the Galactic plane are presented in Galactic coordinates as 3x2 degree tiles. Each tile covers a Galactic latitude range of -1 to +1 degrees, with a longitude centre indicated by the map's filename.

The maps show the cumulative annotations of more than 35,0000 user drawings of large infrared bubbles on NASA Spitzer data from the Milky Way Project (Simpson, et. al, 2012 MNRAs, in press). Each annulus drawn by each user is given an opacity of 2.5% (0.025). In this way regions where 10 users have drawn annuli will have a value of 0.25 and it requires 40 people to draw in the same region for the value to be 1.
