EROS CalVal Center of Excellence (ECCOE)
The EROS Calibration Center of Excellence (ECCOE) is recognized nationally and internationally as a leading organization for effectively improving the accuracy, precision, and efficiency of radiometric, geometric, and spatial characterization, calibration, and cross-calibration of optical remote sensing systems to achieve the highest degree of interoperability of remote sensing data products.
Forty-six years ago, there was a single Earth observation satellite circling the globe – Landsat 1.
By 1988, four countries operated such satellites. In 2018, there were 45 Earth observing satellites launched by September. Another 36 launches are planned this year.
The number of countries operating satellites? That’s swollen to 54.
Over the past five years, private companies have launched hundreds of shoebox-sized Earth observation “cubesat” satellites into space with promises of high-resolution daily imagery.
The rapid emergence of smallsats begs the question: What role does a legacy satellite like Landsat play in the development and use of these relatively inexpensive orbiters?
In the world of optical Land Remote Sensing, USGS EROS’ work in the calibration of Landsat data stands up at the top as the best in the world.
Radiometric characterization of Landsat Collection 1 products
Landsat data in the U.S. Geological Survey (USGS) archive are being reprocessed to generate a tiered collection of consistently geolocated and radiometrically calibrated products that are suitable for time series analyses. With the implementation of the collection management, no major updates will be made to calibration of the Landsat sensors...Micijevic, Esad; Haque, Md. Obaidul; Mishra, Nischal
Landsat-8 TIRS thermal radiometric calibration status
The Thermal Infrared Sensor (TIRS) instrument is the thermal-band imager on the Landsat-8 platform. The initial onorbit calibration estimates of the two TIRS spectral bands indicated large average radiometric calibration errors, -0.29 and -0.51 W/m2 sr μm or -2.1K and -4.4K at 300K in Bands 10 and 11, respectively, as well as high variability...Barsi, Julia A.; Markham, Brian L.; Montanaro, Matthew; Gerace, Aaron; Hook, Simon; Schott, John R.; Raqueno, Nina G.; Morfitt, Ron
Statistical relative gain calculation for Landsat 8
The Landsat 8 Operational Land Imager (OLI) is an optical multispectral push-broom sensor with a focal plane consisting of over 7000 detectors per spectral band. Each of the individual imaging detectors contributes one column of pixels to an image. Any difference in the response between neighboring detectors may result in a visible stripe or band...Anderson (CTR), Cody; Helder, Dennis; Jeno (CTR), Drake
