  skos:definition """The Return Beam Vidicon (RBV) consisted of three TV-like cameras
which used color filters to provide multispectral images in EM
bands centered in the blue-green, yellow-red, and red-IR. This
sensor failed early on the ERTS-1 and never came into routine
use. However, a four-camera RBV on Landsat-3 was a panchromatic
(0.505 - 0.750 m) version that provided four contiguous images
at 30 m (98ft) resolution; each image comprises approximately
one-quarter of a full Landsat MSS scene).
