Abstract
The NSW Department of Primary Industries recently acquired over 200,000 line kilometres of high-resolution airborne geophysical data. As part of this process, significant resources were allocated in monitoring the data quality, which resulted in contractors delivering data to a very high standard. Upon release of the new data, it was timely to update the state-wide grids for magnetic, radioelement, gravity and digital elevation data. After a mammoth effort in overcoming problems in merging aerially extensive data sets, merged state-wide grids of geophysical data is now available as a set of four DVDs. Novel approaches in imaging aeromagnetic data in the Broken Hill region are assisting in the interpretation of the geology and structure in poorly outcropping areas.https://doi.org/10.1071/ASEG2007ab123
