The Bochum Galactic Disk Survey (GDS) is an on-going project dedicated to monitor the variability of the intermediately bright stellar population in a 6^\circ wide stripe along the Galactic plane.
Started in 2010 it currently comprises light curves for \sim 2\times 10^7 stars in Sloan r and i as well as average brightnesses in UBVz. Of those we currently find 110.456 stars to be variable in brightness.
The project aims at detecting any kind of stellar variability and providing high-quality light curves for their further analysis.
In particular, we focus on the variability during the star formation process as well as the stellar multiplicity as a function of mass as witnessed by eclipsing binaries, and the determination of Galactic Cepheid distances.
