Abstract

A new technique is described and evaluated for radiometrically rectifying each of several Landsat images of a scene to common sensor calibration, illumination, and atmospheric conditions. This radiometric rectification technique identifies radiometric control sets, i.e., sets of scene landscape elements with mean reflectance expected to change little with time. The average digital count values of the radiometric control sets in each image are used to calculate a linear transform relating digital count values between images. The technique is evaluated empirically with Landsat Thematic Mapper (TM) images of a scene for which surface reflectance and atmospheric optical depth data are available. It is concluded that radiometric rectification is a useful adjunct to atmospheric radiative transfer codes and sensor calibration approaches in processing and analyzing satellite remote sensing images, and it provides a clear alternative for retrospective remote sensing studies where no in situ atmospheric optical property data are available.
