In April 1995 the Dominion Radio Astrophysical Observatory, in collaboration with a consortium of university astronomers, began a project to image the atomic hydrogen and radio continuum emission from the interstellar medium of the Milky Way galaxy. By constructing a mosaic of 190 synthesis fields, the survey will cover the region 75 < L < 145 degrees and -3 < B < +5 degrees, with angular resolution of one arcminute. The atomic hydrogen cube will yield a 3-dimenional images with spatial resolution of order 1 pc over regions several kiloparsec in extent. In the continuum, full Stokes I, Q, U and V images are produced at 1420 MHz and a Stokes I at 408 MHz.
The CGPS survey is being carried out as part of an international collaboration to image the Milky Way, at a common resolution, in emission from all major constituents of the interstellar medium: the neutral atomic gas, the molecular gas, the ionized gas, dust and relativistic plasma. For many of these constituents the angular resolution of the images will be more than a factor of 10 better than any previous studies. We present initial images from the project as well as highlights of some early scientific results.
