Landsat 9 pre-launch sensor characterization and comparison with Landsat 8 results [PDF]

Sensors, Systems, and Next-Generation Satellites XXIII, 2019
Landsat 9 is planned for launch in December 2020 to continue the mission of observing changes on the Earth’s surface that began in 1972 with the launch of Landsat 1. Like Landsat 8, Landsat 9 will carry two imaging instruments: Operational Land Imager 2 (OLI-2), designed and built by Ball Aerospace**, and Thermal Infrared Sensor 2 (TIRS-2 ...

Antarctic-wide annual ice flow maps from Landsat 8 imagery between 2013 and 2019

International Journal of Digital Earth, 2021
Ice velocity constitutes a key parameter for quantifying ice-sheet discharge rates and is thus crucial for improving the coupled models of the Antarctic ice sheet towards accurately predict its contribution to future global sea-level rise.

Radiometric cross-calibration of Göktürk-2 with Landsat 8

2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
Radiometric calibration studies need to be done during the life-time of a satellite. In this paper, reflectance-based cross calibration was conducted at Tuz Golu LandNet site in 2016 using Gokturk-2 and Landsat 8 imageries. Using near-simultaneous images of the satellites under the same atmospheric conditions reduces the effect caused by reflection ...

Applications of Landsat-8 Data: a Survey

International Journal of Engineering and Technology, 2018
Landsat 8 was launched in 2013 by the National Aeronautics and Space Administration (NASA). On board of the Landsat 8 is the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS). Data for visible, panchromatic band, short-wave infrared spectral bands are collected by the OLI while TIRS collect images in the thermal region.
