Landsat-8 Operational Land Imager Design, Characterization and Performance [PDF]
The Operational Land Imager (OLI) on Landsat-8 represents a generational change from heritage Landsat instruments in its design, while it maintains data continuity with the 40+ year Landsat data archive. It preserves the 30-m ground sample distance, 185-km swath width and VIS/NIR/SWIR spectral bands.

Radiometric Calibration Methodology of the Landsat 8 Thermal Infrared Sensor [PDF]
The science-focused mission of the Landsat 8 Thermal Infrared Sensor (TIRS) requires that it have an accurate radiometric calibration. A calibration methodology was developed to convert the raw output from the instrument into an accurate at-aperture radiance.

ABSTRACT Understanding the relationships among land degradation, ecosystem functioning and human well‐being is essential for conserving tropical high‐mountain ecosystems. This study examined the relationships among land degradation, Cultural Ecosystem Services (CES), ecosystem disservices (EDS) and visitor perceptions at Laguna Colorados in the Sumapaz

Landsat-8 Operational Land Imager Radiometric Calibration and Stability [PDF]
The Landsat-8 Operational Land Imager (OLI) was radiometrically calibrated prior to launch in terms of spectral radiance, using an integrating sphere source traceable to National Institute of Standards and Technology (NIST) standards of spectral irradiance. It was calibrated on-orbit in terms of reflectance using diffusers characterized prior to launch

ABSTRACT Soil organic matter (SOM) is a key indicator of land degradation and soil functioning. It plays an essential role in nutrient cycling, soil structure, and long‐term agroecosystem resilience. The variations of surface cover, soil moisture and soil texture heterogeneity will affect the accuracy of SOM remote sensing mapping. This study developed

Landsat-8 operational land imager on-orbit radiometric calibration [PDF]
The Operational Land Imager (OLI), the VIS/NIR/SWIR sensor on the Landsat-8 has been successfully acquiring Earth Imagery for more than four years. The OLI incorporates two on-board radiometric calibration systems, one diffuser based and one lamp based, each with multiple sources. For each system one source is treated as primary and used frequently and
