Landsats 1 and 2 supported two sensor systems, the Return Beam Vidicon (RBV) and the Multi-Spectral Scanner (MSS).
The RBV consisted of three TV-like cameras which used colour filters to provide multispectral bands centred in the blue-green, yellow-red, and red-IR regions of the spectrum. However, this sensor failed early on Landsat 1 (ERTS 1) and never came into routine use. Note that a panchromatic four camera RBV on Landsat 3 provided four contiguous images at 30 m resolution.
The MSS has operated on all Landsat spacecraft up to and including Landsat-5 to maintain continuity. Table 1 provides summary information about the Landsat MSS.
|Instrument||Wavebands*||Spectral Response||Resolution||Swath Width|
4: 0.5 - 0.6um
5: 0.6 - 0.7um
6: 0.7 - 0.8um
7: 0.8 - 1.1um
The Landsat MSS scanning arrangement is illustrated in Figure 1.
Applications of MSS data
Landsat MSS data has been widely used for land applications. However do you know what the mission specifics for each of the wavebands originally was?
