Product Name	Product Definition	Product Units	Spatial Resolution	Temporal Resolution	Coverage Area	Product Format	Period of Product Availability
Orthorectified MSS image/data	These Landsat/MMS data were orthorectified, using geodetic and elevation control data to correct for positional accuracy and relief displacement. Large blocks of Landsat data were adjusted through a patented procedure that uses pixel correlation to acquire tie-points within the overlap area between adjacent Landsat images.	radiances	57 m	16-18 day repeat cycle	Global	GEOTIFF	1972-1987
Orthorectified TM Mosaic image/data	These Landsat/TM data were orthorectified, using geodetic and elevation control data to correct for positional accuracy and relief displacement. Large blocks of Landsat data were adjusted through a patented procedure that uses pixel correlation to acquire tie-points within the overlap area between adjacent Landsat images.	radiances	28.5 m	16 day repeat cycle	Global	GEOTIFF	1985-1996
Orthorectified ETM+ image/data	These data have been orthorectified for co-registration with the earlier Landsat TM coverage.	radiances	28.5 m	16 day repeat cycle	Global	GEOTIFF	1999-2001
Orthorectified ETM+ Pan-sharpened image/data	Consist of pan-sharpened versions of the ETM+ scenes above. The pan-sharpening process involved a resolution merging process, which allows the fusion of the higher-resolution panchromatic band (8) with selected lower-resolution multispectral bands (7,4,2) to create a higher-resolution ("pan-sharpened") color image.	radiances	14.25 m	16 day repeat cycle	Global	GEOTIFF	1999-2001
