Class GranuleAggregation

java.lang.Object

edu.wisc.ssec.mcidasv.data.hydra.GranuleAggregation

All Implemented Interfaces:

MultiDimensionReader

public class GranuleAggregation
extends Object
implements MultiDimensionReader

This file should be renamed - think about that Tommy. This file needs to implement the same signatures NetCDFFile does, but for aggregations of consecutive granules.
