Magnetic Re-Processing example
The benefits of re-processing can be seen by the much increased detail in the image of the TMI. The delivered grid has been over-smoothed by a long wavelength filter that has introduced linearity in the NE-SW direction.
Gradient Gridding example
The improvement in resolution by including the gradients in gridding can be seen in the images below. The grids both have been gridded with cell size 20m. Flying height was 20m.
