Operational Aspects of Landsat 8 and 9 Geometry
Remote Sensing, 2023 Landsat 9 (L9) was launched on 27 September 2021. This spacecraft contained two instruments, the Operational Land Imager-2 (OLI-2) and Thermal Infrared Sensor-2 (TIRS-2), that allow for a continuation of the Landsat program and the mission to acquire ...

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 ...

A Study of the Land Cover of Razzaza Lake during the Past 25 Years Using Remote Sensing Methods
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023 In this study, the Earth's surface was studied in Razzaza Lake for 25 years, using remote sensing methods. Images of the satellites Landsat 5 (TM) and 8 (OLI) were used to study and determine the components of the land cover. The study covered the years

International Journal of Applied Earth Observations and Geoinformation, 2023 One important mission of the newly launched Landsat-9 is to collaborate with Landsat-8 to reduce the revisit period of Landsat Earth observations to eight days. This requires a high level of consistency between the two satellite data.
