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 almost 200 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.
Approximately 50% of the DRAO observations have now been completed, and the
first complete mosaic images were created in December 1997. This paper
presents a description of the survey project and highlights of the discoveries
and results from these initial data products.
