Specifically, this survey contains: 1. Minimally processed (raw) AEM data and raw/processed magnetic data provided by SkyTEM 2. Fully processed AEM data used as input to inversion 3. Laterally constrained inverted resistivity models 4. Point-data estimates of bedrock depth derived from the AEM models 5. Interpolated magnetic and bedrock depth grids Note: To make the size of this example more managable, some of the input datasets have been downsampled relative to the source files in the data release referenced below.
