Australia-wide high passed Radiometric image

Abstract

A full width image of the radiometrics of Australia is offered as a standard source for radiometric images of subset areas. High pass filtering each of the component grids has allowed colour transforms to be obtained for the whole continent that approximate the transforms that would be required to equalise each zoomed subset. Standard practice for radiometric mapping has been to cut subset areas from the separate radiometric grids and use a proprietary image processing software to obtain an equalised colour stretch of the area. The Australia wide radiometric image already has the image processing completed, so the subset can be taken of the image itself. Consequently, specialist software is not necessary to obtain sufficiently equalised images of the radiometrics of any area within Australia. The image is available as a TIFF file on GADDS, from which subsets can be downloaded and studied in ordinary office software.
