           Summary: Need ASC grid Utilities actor
           Product: Kepler

Currently there are actors (developed for the ENM example) for working with ASC
grids. Such spatial grid actors allow rescaling, merging, etc. However, several
simple functions, such as simply finding the value at some location are not
directly supported; i.e. given a (lat, long) what is the grid value? [Such
operations are buried inside more complex actors, but not available to the
external user.]

At the ENM workshop in Albuquerque in Jan. 2008, an actor with a simpler
interface that could return values at an input location was requested. This
would be useful for building new measures of omission and commission or other
calculational purposes. Other general purpose utility operations might be
returning maximum, minimum, or average values.
