Landsat 9 detects more subtle differences than its predecessor, especially over darker areas such as water or dense forests. With this improved radiometric resolution, Landsat 9’s OLI-2 can differentiate 16,384 shades of a given wavelength. In comparison, Landsat 8 provides 4,096 shades. Landsat...
Both instruments have sensors with moderate spatial resolution—15 m (49 ft), 30 m (98 ft), and 100 m (328 ft)depending on spectral band—and the ability to detect a higher range in intensity than Landsat 8 (14-bitradiometric resolution vs. Landsat 8's 12-bit radiometric resolution). ...
Operational Land Imager 2 (OLI-2): 9 spectral bands as Band 1 to 9 (15m, 30m, and 60m) Thermal Infrared Sensor 2 (TIRS-2): 2 thermal bands as Band 10 and 11 (100m spatial resolution) Radiometric Resolution: 14-bit Launch Date: September 27, 2021 ...

radiometric accuracy and stability, as well as the ability to perform solar and lunar calibrations. Google翻译:OLI-2 设计是 Landsat 8 的 OLI 的副本。 OLI-2 仪器将提供与先前 Landsat 光谱、空间、辐射测量和几何质量一致的可见光和近红外/短波红外 (VNIR/SWIR) 图像。然而,不同之处在于,Landsat 9 ...
4. Radiometric Resolution Thesensitivity that a sensor has to the magnitude of electromagnetic energyis called itsradiometric resolution. The higher the radiometric resolution, the more precisely a sensor can measure the EM radiation it detects. ...
Combining images from multiple Earth Observing (EO) satellites increases the temporal resolution of the data, overcoming the limitations imposed by low revisit time and cloud coverage. However, this requires an intercalibration process to ensure that there is no radiometric difference in t...
The OLI2 generates data in 9 spectral bands by sub-selecting the operational detectors within the focal plane array for each spectral band. This sub selection of detectors, also known as the operational flight detector-select-map, was determined pre-launch based on various radiometric performance ...
