A Study on the Difference of LULC Classification Results Based on Landsat 8 and Landsat 9 Data

Sustainability, 2022
Landsat 9 enhances the radiation resolution of the operational land imager from the 12 bits of Landsat 8 to 14 bits. The higher radiation resolution improves the sensitivity of the sensor to detect many subtler differences, especially in the case of dense forests or water.
