SUMMARY The spacing of interpolation supports in the Earth can be optimized to fit local resolution by connecting natural neighbours with springs of length equal to the local resolving length and minimizing the potential energy of the system. A triangulation scheme for the starting configuration of the grid is implemented to avoid that the optimization converges to an unacceptable local minimum in the energy.
