Figure 38. The 3-D model obtained from the inversion of the Lernacken Sludge deposit
survey data set displayed with the Slicer/Dicer program. A vertical exaggeration factor of 2 is
used in the display to highlight the sludge ponds. Note that the colour contour intervals are
arranged in a logarithmic manner with respect to the resistivity.
