We present a study of the galactic plane region l 28.5, b 0.0 from mid-infrared to X-ray wavelengths. We have produced a source list for a combination of Chandra X-ray (Ebisawa et al. 2005), optical BVR (WIYN 0.9-m), near-IR JHK (2MASS), and mid-IR [3.6],[4.5],[5.8],[8.0] (Spitzer/GLIMPSE) data. Forty-four sources have X-ray, optical and infrared information, and 83 have at least infrared and x-ray fluxes. We present information on the nature of these sources by comparing the infrared SEDs to a extensive grid of stellar and YSO models using a library and fitting algorithm of Robitaille et al. (2006). Out of 12122 IR sources evaluated by the fitter, 479 sources have SED's consistent with young stellar objects (YSOs). We find that only three X-ray sources have SEDs consistent with YSOs. We also note that only 2 hard X-ray sources are detected in the optical bands.
