1 Multispectral Remote Sensing Systems
Landsat SPOT Weather satellites - GOES - AVHRR High-resolution satellite - IKONOS Hyper-spectral sensor - AVIRIS EOS-Terra instruments - ASTER - MODIS

2 Landsat Program Originally called (ERTS) - Earth Resources Technology Satellite. First satellite launched in 1972 Broad scale repetitive surveys of the landscape Visible, NIR spectral bands (Landsats 1,2,3), and MIR and Thermal (Landsats 4 and 5) Sensors: Multispectral scanner (MSS) Return beam vidicon (RBV) Thematic Mapper (TM) Enhanced Thematic Mapper Plus (ETM+)

3 Chronological Launch and Retirement History of the Landsat Satellite Series

4 Landsat Multispectral Scanner (MSS)

5 Inclination of the Landsat Orbit to Maintain A Sun-synchronous Orbit
Inclination = 98.2degree

6 Landsat Multispectral Scanning System (MSS) Orbit

7 Orbit Tracks of Landsat 1, 2, or 3 During A Single Day of Coverage

8 Landsat 4 and 5 Worldwide Reference System(WRS)

9 Landsat 4 and 5 Platform with Associated Sensor and Telecommunication Systems

10 Spectral and Spatial Resolution of the Landsat Multispectral Scanner (MSS), Landsat 4 and 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), SPOT 1, 2, and 3 High Resolution Visible (HRV), and SPOT 4 High Resolution Visible Infrared (HRVIR) Sensor Systems

11 Seven Bands of Landsat Thematic Mapper Data of Charleston, SC, Obtained on February 3, 1994

17 Band 1 minus Band 2. The ocean and living plants reflect more deep blue-violet hues. Most plants produce surface wax (for example, the frosty coating on fresh plums) as they grow, to reflect harmful ultraviolet light away.

18 Band 9 (covering only a tiny slice of EMR) is just for clouds
Band 9 (covering only a tiny slice of EMR) is just for clouds! Here it’s picking up fluffy cumulus clouds, but it’s designed especially for cirrus clouds.
