Abstract

During 2000/2001 a new automatic method of merging gridded airborne magnetic data was developed by Geoscience Australia. This involves considering all the grids at once, and treating the requirement that they match together in the best possible way as a single inverse problem. Both `DC' and low-order polynomials can be applied to grids during the process. The program Gridmerge undertakes these tasks, as an independent entity within the Intrepid geophysical processing system. Regional compilations of airborne magnetic data (from the Yilgarn area of Western Australia, the Tanami-Arunta area of the Northern Territory, the Curnamona region of South Australia and New South Wales and all of Western Australia) are used to compare the results of Gridmerge with the test datasets.
