public class NASADataset
extends Rectangle

A class that contains meta information about a NASA dataset extracted from an HDF file. This information is extracted from the meta data in the HDF file and includes: - Spatial boundaries of the dataset - Date time on which the data was taken - Name of the cell in the Sinusoidal grid - Name of the dataset in the HDF file - Resolution of the dataset This class extends Rectangle to make it compatible to use as a key with SpatialInputFormat
