The SMPGS is a wide-field, wide-band 1.3 GHz radio continuum survey ($251^\\circ \\leq l \\leq 358^\\circ$ and $2^\\circ \\leq l \\leq 61^\\circ$ at $\\quad |b| \\leq 1^\\circ.5$) that has enabled us to trace the diffuse emission enveloping recently formed massive stars. Our multifrequency synthesis images reveal faint and extended emission that was previously overlooked by $\\textrm{H}\\scriptstyle\\mathrm{II}$ region surveys.
