We have successfully conducted the Chandra Multiwavelength Plane (ChaMPlane) Survey for four years. ChaMPlane is a project to systematically identify and analyze the serendipitous X-ray sources in the Chandra archive in order to determine the populations of accretion-powered binaries in the Galactic Plane. The ChaMPlane Optical Survey is the optical follow-up using the CTIO and KPNO 4m telescopes to identify counterparts of the Chandra sources for subsequent spectroscopy observations and classifications. In the past four years, we have observed 43 Mosaic fields (FoV: 36\prime\times36\prime) in V, R, I and H\alpha bands which cover 15 square degrees and 99 Chandra ACIS observations in the galactic plane. For the ~8000 detected serendipitous X-ray sources, a significant fraction (more than 50% for fields with NH < 5\times1021) of their optical counterparts are identified. Spectroscopic follow-ups for those optical counterparts and H\alpha emission sources have been conducted on 19 of the fields using the WIYN (3.5-m), Magellan (6.5-m), MMT(6.5-m) and CTIO(4-m) telescopes. A number of new CVs and many new AGNs have been found. As one of the NOAO Long Term survey programs, ChaMPlane is delivering the final stacked and calibrated deep images to NOAO archive, which will be available to the public. We have also developed a virtual observatory node to facilitate access and on-line analysis of ChaMPlane data.
