Ciao Ian,
another option is to use the zonal stats operation or even better the process.
The operation is part of the coverage module:

http://stackoverflow.com/q/27761590/439194 - asks how to "filter" a grid
coverage. I've had a go at answering it but my method (using a histogram)
feels clunky, but I can't think of a better way to do it.
Any of you coverage guys want to chip in? My only other thought was to
produce a new operatio
