Automatically Monitoring Impervious Surfaces Using Spectral Generalization and Time Series Landsat Imagery from 1985 to 2020 in the Yangtze River Delta

Figure 10

The density plots for NIR surface reflectance of impervious surfaces in the summer of 2020 ( axis) against the corresponding NIR surface reflectance at other periods ( axis) before applying the relative radiometric normalization. The blue dashed lines and the black lines are the 1 : 1 lines and linear regression fitted lines, respectively.
