Swath overlap (or sidelap) varied from 14 percent at the Equator to a maximum of approximately 85 percent at 81° north or south latitude
Sensors Return Beam Vidicon (RBV)
The RBV system on Landsat 3 used two cameras, mounted side-by-side, with panchromatic spectral response and higher spatial resolution (40 m) to complement the multispectral coverage provided by the Multispectral Scanner (MSS). Each of the cameras produced a swath of about 90 km (for a total swath of 180 km).
40 m resolution from 2, 80 m resolution cameras
Two cameras with a panchromatic spectral response
Data: 3.5 MHz video
Multispectral Scanner (MSS)
Five spectral bands, including a thermal band:
Band 4 Visible (0.5 to 0.6 µm)
Band 5 Visible (0.6 to 0.7 µm)
Band 6 Near-Infrared (0.7 to 0.8 µm)
Band 7 Near-Infrared (0.8 to 1.1 µm)
Band 8 Thermal (10.4 to 12.6 µm)
Data: 100 kHz digital
Six detectors for each reflective band provided six scan lines on each active scan
Ground Sampling Interval (pixel size): 57 x 79 m
Other Characteristics
Scene size: 170 km x 185 km (106 mi x 115 mi)
Originally designated Landsat 3; also known as Landsat C
