Yes it is also my understanding. It GeoTools implementation, GridCoverage2D 
(without subclassing) would be a discrete coverage (minus tricky boundary 
issues 
like the ones you mentioned) while Interpolator2D would be a continuous 
coverage. But at this time GeoTools does not implement ISO interfaces that way. 
However this is something we would like to do in the future.
