Landsat 5 TM Satellite Image Data

Multispectral Scanner (MSS)

-Acquisitions of Landsat 5 MSS data over the United States ceased in 1992; global acquisitions ended in 1999. Limited acquisitions were made from June 2012 through January 2013, after the loss of the TM sensor on the satellite.

-Four spectral bands (identical to Landsat 1 and 2): -Band 4 Visible green (0.5 to 0.6 µm, -Band 5 Visible red (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)

-Six detectors for each spectral band provided six scan lines on each active scan

-Ground Sampling Interval (pixel size): 57 x 79 m

Thematic Mapper (TM)

-Added the mid-range infrared to the data

-Seven spectral bands, including a thermal band: Band 1 Visible (0.45 - 0.52 µm) 30 m, Band 2 Visible (0.52 - 0.60 µm) 30 m, Band 3 Visible (0.63 - 0.69 µm) 30 m, Band 4 Near-Infrared (0.76 - 0.90 µm) 30 m, Band 5 Near-Infrared (1.55 - 1.75 µm) 30 m, Band 6 Thermal (10.40 - 12.50 µm) 120 m, Band 7 Mid-Infrared (2.08 - 2.35 µm) 30 m.

-Ground Sampling Interval (pixel size): 30 m reflective, 120 m thermal

Landsat 7 ETM Satellite Image Data

-Enhanced Thematic Mapper Plus (ETM+)

-Eight spectral bands, including a pan and thermal band: Band 1 Visible (0.45 - 0.52 µm) 30 m, Band 2 Visible (0.52 - 0.60 µm) 30 m, Band 3 Visible (0.63 - 0.69 µm) 30 m, Band 4 Near-Infrared (0.77 - 0.90 µm) 30 m, Band 5 Near-Infrared (1.55 - 1.75 µm) 30 m, Band 6 Thermal (10.40 - 12.50 µm) 60 m Low Gain / High Gain, Band 7 Mid-Infrared (2.08 - 2.35 µm) 30 m, Band 8 Panchromatic (PAN) (0.52 - 0.90 µm) 15 m.

-Ground Sampling Interval (pixel size): 30 m reflective, 60 m thermal

-Added the Band 6 Low and High gain 60 m thermal bands

-On-board calibration was added to Landsat 7: a Full Aperture Solar Calibrator (FASC) and a Partial Aperture Solar Calibrator (PASC), in addition to the 2 calibration lamps

Landsat 8 LDCM Satellite Image Data

-Operational Land Imager (OLI)

-Nine spectral bands, including a pan band: Band 1 Visible (0.43 - 0.45 µm) 30 m, Band 2 Visible (0.450 - 0.51 µm) 30 m, Band 3 Visible (0.53 - 0.59 µm) 30 m, Band 4 Red (0.64 - 0.67 µm) 30 m, Band 5 Near-Infrared (0.85 - 0.88 µm) 30 m, Band 6 SWIR 1(1.57 - 1.65 µm) 30 m, Band 7 SWIR 2 (2.11 - 2.29 µm) 30 m, Band 8 Panchromatic (PAN) (0.50 - 0.68 µm) 15 m, Band 9 Cirrus (1.36 - 1.38 µm) 30 m.

-Thermal Infrared Sensor (TIRS)

-Two spectral bands: Band 10 TIRS 1 (10.6 - 11.19 µm) 100 m, Band 11 TIRS 2 (11.5 - 12.51 µm) 100 m.
