Abstract

Summary

We present examples of integration of ancillary information to AEM data from different surveys around the world. The data enters the inversion as apriori extra parameter, either from a grid, or from a point source. We use the spatially constrained inversion to migrate the apriori information across the dataset. This approach allows also using the apriori information to re-calibrate the AEM dataset, solving for extra calibration parameters, along the lines of holistic inversion.
