INTRODUCTION

This product was created by the United States Geological Survey (USGS) and contains 
EO-1 data files in Hierarchical Data Format (HDF). EO-1 was launched as a one-year 
technology demonstration/validation mission. After the initial technology mission 
was completed, National Aeronautics and Space Administration (NASA) and the USGS 
agreed to the continuation of the EO-1 program as an extended mission. Information 
about the EO-1 satellite and the Hyperion sensor are available at the USGS and NASA 
web sites:
http://eo1.usgs.gov 
http://eo1.gsfc.nasa.gov


FORMAT FOR THE LEVEL 0

The Hyperion data are provided in standard HDF Version 4.1 (release 5),
written as band-interleaved-by-line (BIL) files stored in 16-bit signed integer 
radiance values. Level 0 data is neither resampled nor geometrically
corrected or registered.


FORMAT FOR THE LEVEL 1R

The Hyperion data are provided in standard HDF Version 4.1 (release 5),
written as band-interleaved-by-line (BIL) files stored in 16-bit signed integer 
radiance values.


ORGANIZATION FOR THE LEVEL 0

The Hyperion data product consists of a metadata file (.MET), an HDF datasets file 
(.L1R), and multiple ancillary files (.hdf).


ORGANIZATION FOR THE LEVEL 1R

The Hyperion product consists of a metadata file (.MET), an HDF datasets file 
(.L1R) (which includes image data, spectral center wavelengths, spectral 
bandwidths, gain coefficients, and a flag mask), and an ENVI-formatted header 
file (.hdr).

The file naming convention is as follows:

EO1SPPPRRRYYYYDDDXXXML_GGG_VV  where:
	EO1	= Satellite
	S	= Sensor (H=Hyperion, A=ALI)
	PPP	= Target WRS Path
	RRR	= Target WRS Row
	YYYY	= Year of acquisition
	DDD	= Julian day of acquisition
	X	= (0=off; 1=on) Hyperion
	X	= (0=off; 1=on) ALI
	X	= (0=off; 1=on) AC
	M	= Pointing Mode (N=Nadir; P=Pointed within path/row, 
		  K=Pointed outside path/row
	L	= Scene Length (F=Full scene, P=Partial scene, Q=Second
		  partial scene, S=Swath)
	GGG	= Ground/Receiving Station
	VV	= Version Number
