EROS Leads Dialogue on Future of Earth Observation

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.

Landsat Adds Value, Reliability to Cubesat Imagery

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?

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...

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...

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...
