| Abstract: | Relative radiometric normalization is a prerequisite for multi‐temporal remotely sensed data analysis. Dark object subtraction (DOS) and pseudo‐invariant feature (PIF) methods are two commonly employed scene‐based methods for relative radiometric normalization. Both these methods have known limitations. The authors describe a soil line transformation method for multi‐date relative radiometric normalization, which circumvents the limitations of the DOS and PIF methods. |
