Answer 1

Yes, I think spatial-interpolation should be made a synonym of interpolation.

Clearly, spatial interpolation is a subset of interpolation, but in the context of a site about GIS, there is little value in trying to tease the two apart.

The interpolation tag is already used as a de facto master synonym, so let's just make it official.
