Description

PiecewiseBicubicSplineInterpolatingFunction is not able to interpolate if the value we want to calculate is out of the points/values. Other libs provide functionality to make some extrapolation.
In geospatial analysis, for example it is a must have feature, because the locations of points and values are almost always not at the border of the shape that we want to interpolate.
