Example 16. There are several ways to interpolate (x,y,z) data in GMT. The simplest method is triangulation, using linear triangular facets as building-blocks. Gridding with minimum curvature splines is also a popular option; some of the ringing can be reduced by applying tension. One could also use triangulation as a starting method and modify it later with filtering.
