River Bathymetry Retrieval From Landsat-9 Images Based on Neural Networks and Comparison to SuperDove and Sentinel-2

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The Landsat mission has kept an eye on our planet, including water bodies, for 50 years. With the launch of Landsat-9 and its onboard Operational Land Imager 2 (OLI-2) in September 2021, more subtle variations in brightness (14-bit dynamic range) can be ...

Evaluating the consistency of surface brightness, greenness, and wetness observations between Landsat-8 OLI and Landsat-9 OLI2 through underfly images

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.
