I have been struggling to extrapolate beyond the extent of the point features input into the IDW tool of ArcGIS Pro.
I believe IDW interpolation is the method for me, i just need the process to extend beyond the input points slightly to fit a bigger area.
Specifying a mask in the environment settings seems only to clip the same extent (that is that of the input points), to the mask.
Answer
It appears you cannot extrapolate using IDW interpolation. Spline was a sufficient substitute and can be extrapolated.
