Tilt Depth Interpretation

The tilt depth interpretation is a technique for calculating depths to vertical sided bodies from the magnetic tilt angle. As such it required magnetic data as input.

This works on the principle that the distance between the -45 degree and 45 degree tilt angle is twice the distance to the body. This zone of interest is highlighted on the map.

What is important to note is that this technique works best with data which has been reduced to the pole. For this reason, RTP has been built into the module.

The results can be output to a text file, with columns x, y, id and depth. In this case, id refers to a contour id where the tilt angle is equal to zero.
