NOTA BENE

• There are three sensors on this platform. Advanced Land Imager (ALI), Hyperion and Linear Etalon Imaging Spectrometer Array (LEISA) Atmospheric Corrector (LAC).
• There is a baseline mission and an extended mission. The EO-1 Extended Mission is chartered to collect and distribute ALI multispectral and Hyperion hyperspectral products in response to Data Acquisition Requests (DARs). Under the Extended Mission provisions, image data acquired by EO-1 are archived and distributed by the USGS Center for Earth Resources Observation and Science (EROS) and placed in the public domain.

ALI Instrument¹

• The ALI instrument on EO-1 was used to validate and demonstrate technology for the Landsat Data Continuity Mission (LDCM). The image data is provided in 16-bit radiance values. These bands have been designed to mimic six Landsat bands with three additional bands covering 0.433-0.453, 0.845-0.890, and 1.20-1.30 µm.

Product Name	Product Definition	Product Units	Spatial Resolution	Temporal Resolution	Coverage Area	Product Format	Period of Product Availability
ALI Radiometrically corrected	Radiometrically (i.e., direct calibration of the radiometer) corrected only.	Radiance	Pixel size 30-meter resolution for the multispectral pixels and 10-meter resolution for the panchromatic pixels. The ground swath width of 37 km	16-day potential repeat cycle for scenes within the current flight path (nadir).	Global	EOS-HDF	2001-present
ALI geometrically corrected	Radiometrically corrected and resampled for geometric correction and registered to a geographic map projection.	Radiance	Pixel size 30-meter resolution for the multispectral pixels and 10-meter resolution for the panchromatic pixels. The ground swath width of 37 km	16-day potential repeat cycle for scenes within the current flight path (nadir).	Global	EOS-HDF	2001-present
ALI terrain corrected "stitched"	Radiometrically corrected and resampled for geometric correction and registration to a geographic map projection. The image data is also ortho-corrected using digital elevation models (DEM) to correct parallax error due to local topographic relief. The source of DEM used will vary according to local availability of elevation information.	Radiance	Pixel size 30-meter resolution for the multispectral pixels and 10-meter resolution for the panchromatic pixels. The ground swath width of 37 km	16-day potential repeat cycle for scenes within the current flight path (nadir).	Global	EOS-HDF	2001-present

Hyperion Instrument¹

• The image data from the Hyperion Instrument are provided in 16-bit radiance values. collects 220 unique spectral channels ranging from 0.357 to 2.576 micrometers with a 10-nm bandwidth.

Product Name	Product Definition	Product Units	Spatial Resolution	Temporal Resolution	Coverage Area	Product Format	Period of Product Availability
HyperionI Radiometrically corrected	Radiometrically (i.e., direct calibration of the radiometer) corrected only.	Radiance	The instrument has 30 meters resolution. The standard scene width is 7.7 kilometers. Standard scene length is 42 kilometers, with an optional increased scene length of 185 kilometers	16-day potential repeat cycle for scenes within the current flight path (nadir).	Global	EOS-HDF	2001-present

1. The instruments on EO-1 was used to validate and demonstrate technology for the Landsat Data Continuity Mission (LDCM). Therefore, the kinds of data products obtained from Landsat can be obtained using data from the instruments on EO-1.
