Thank Rolf, I am aware of the extrapolation possibilities within the interpolation packages within akima but this interpolation often leads to unrealistic results for my sedimentary units. Therefore I would like to be able to just apply the interpolation to the thickness measurements within the c

Hi there, I have been using the Tps function (within the Fields package) for a while now to interpolate different sedimentary units. Due to the method of formation of the units I know that at some edges the thickness of the unit decreases to zero. I was wondering if there was someway to specify t
