Radiometric stitching

Abstract

Large scale stitching of radiometric data has often been found to be intractable, its solutions elusive. The procedures used in the stitching of the successful Northern Territory Radiometric Map are described in this paper. Recommendations are made to facilitate radiometric stitching and some pitfalls are identified. A convenient way of expressing the spatial detail of the total count has been found by substituting its high-passed form into the intensity layer of ternary images. An unexpected result of the merging and inclusion of the total count in the images has been the realisation of detail in the regolith between outcrops.
