Abstract :
There are many remote sensing studies where it is desirable to have a radiometrically matched time series of images or image mosaics., This paper examines the use of bi-directional reflectance distribution function (BRDF) models for radiometric correction of Landsat 7 ETM+ imagery. It describes a simple radiometric correction method which combines: a top-of-atmosphere reflectance adjustment with an empirical BRDF model. The model parameters were derived from an overlapping sequence of Landsat 7 images
