This dataset spans twelve 1:250K geological map sheets, from Cobar in the northwest to Goulburn in the south east. Within these bounds, the geophysical merges for magnetics, radiometrics, and DEM are all produced at a grid cell resolution of 10 m, which is made possible by theFigure 2.Map displaying the area of the Central NSW ultra-high-resolution merge (red).
