ABSTRACT

A new atmospheric correction method for Landsat TM images based on a heuristic tasseled cap-like transformation followed by additional nonlinear transformations to eliminate the soil moisture effects together with atmospheric effects. A comparative study has been done to verify and test the new method that yielded to a conclusion that the usage of the ACABA method provides a fast and reliable atmospheric correction. The new method has been applied to two subimages over different parts of Hungary, and has provided excellent normal optical depth image and a well corrected greenness map.
