  A hybrid JHKs-W1W2W3W4 high-spectral index (alpha) selection scheme was
employed to identify (sub)clusters of class I/f candidate protostars (YSOs) in
WISE observations (the Wide-Field Infrared Survey Explorer). n>10^4 candidate
YSOs were detected owing to WISE's advantageous all-sky spatial coverage, and a
subsample (n~200) of their heavily-obscured host (sub)clusters were correlated
with the Avedisova (2002) and Dias et al. (2002) catalogs of star-forming
regions. Forthcoming observations from the VVV/UKIDSS surveys shall facilitate
the detection of additional protostars and bolster efforts to delineate the
Galactic plane, since the campaigns aim to secure deep JHKs photometry for a
pertinent fraction of the WISE targets lacking 2MASS detections, and to provide
improved data for YSOs near the limits of the 2MASS survey.
