Optical Cartography of the Northern Galactic Plane with IPHAS

Hywel Farnhill (University of Herfordshire, UK )

The INT Photometric H-alpha Survey (IPHAS) recently published its second data release, covering more than 1800 sq. deg. of the Northern Galactic Plane in r', i', and narrow-band Halpha filters. Its broad-band photometry down to 19th magnitude has been used to produce high resolution density maps of the Galactic Plane, with the effects of incompleteness fully accounted for. I will discuss the generation of these data products which will serve as useful tests of Galactic population models and a useful tool for spectroscopic surveys in the Galactic Plane.
