Method Summary

float	getAttribute(Footprint location) Would report the attribute of the model at the given location, but does nothing in this case.

float	getMaxAttribute() Would report the maximum attribute value of the object, but does nothing in this case.
float	getMinAttribute() Would report the minimum attribute value of the object, but does nothing in this case.
SpatialModel	subset(Footprint bounds) Would creates a new spatial model that is clipped to the given bounds, but does nothing in this case.
void	updateBounds() Would force the object to find its new spatial and attribute bounds, but does nothing in this case.
