With Landsat 5 retiring in early 2013, leaving Landsat 7 as the only on-orbit Landsat program satellite, Landsat 8 ensures the continued acquisition and availability of Landsat data utilizing a two-sensor payload, the Operational Land Imager (OLI) and the Thermal InfraRed Sensor (TIRS). Respectively, these two instruments collect image data for ...
OLI structure Satellite image of the Thames Estuary taken by OLI. The Operational Land Imager (OLI) is a remote sensing instrument aboard Landsat 8, built by Ball Aerospace & Technologies. Landsat 8 is the successor to Landsat 7 and was launched on February 11, 2013. [1] OLI is a push broom scanner that uses a four-mirror telescope with fixed ...
Landsat 8 has two sensors with its payload, the Operational Land Imager (OLI) and the Thermal InfraRed Sensor (TIRS). [16] Landsat 9: 27 September 2021: active: 3 years, 4 months and 15 days: Landsat 9 is a rebuild of its predecessor Landsat 8. [17] [18]
Landsat-7: Active NASA and USGS 1999 Images Earth's land surfaces and coastal areas with global coverage at high spatial resolution. [19] Landsat-8: Active NASA and USGS 2013 Follow on to Landsat-7 with improved imager OLI and thermal sensor TIRS. Landsat-9: Active NASA and USGS 2021 Follow on to Landsat-8 with OLI sensor and thermal sensor TIRS-2.
Using 7000 sensors per band (Spectrum band), the OLI on NASA's most recent LandSat (LANDSAT 8) Satellite, will image/view the entire earth every 16 days. Enhanced Thematic Mapper + (ETM+) [6] [7] Used in conjunction with OLI, the ETM + images the Earth in 30m Pixels. To ensure quality, each scan has a correction due to Scan-Line correcting. A ...

In order to compare the two imagers, EO-1 followed Landsat 7 in its orbit by exactly one minute. The ALI's instrument design and onboard technology directly shaped the design of the Operational Land Imager (OLI) on Landsat 8. [3] Other new technologies included: Hyperion imaging spectrometer recording more than 200 wavelengths;
