Iím about to write a class and it occurs to me that itís general enough that someone else may have already something equivalent. It would be either a wrapper or subclass of GeomGridField, and for a given x, y (floats), it would give you a weighted combination of the 4 nearest cells. This is in contrast to the way GeomGridField.toXCoord(x) works, which is to truncate to the nearest integer index, then return the value in that cell. If anyoneís already written this code, Iíd be glad to have it.
