It is announced that positional accuracy of Landsat-8 /OLI: 12 meters circular error, 90-percent confidence, and TIRS - 41 meters circular error, 90-percent confidence. I cannot find the same characteristics for previous Lansats. Can anybody help?
Landsat ETM+ was designed to provide a geometric accuracy of at least 250 meters (1 sigma) in low-relief areas at sea level. However, the use of definitive ephemeris for Level 1G (systematic) correction frequently provides a geometric accuracy within 30-50 meters
Hello, for Landsat 7 try this source: http://landsathandbook.gsfc.nasa.gov/data_properties/index.html

Landsat 7 this source is very use full: http://landsathandbook.gsfc.nasa.gov/data_properties
Many thanks to everybody! I know the real practical positional accuracy basing on 20 years of Landsat images interpretation with the help of field works. It is really about 30 meters (or even less, when it is possible to find a point inside a pixel!). I search an approved published data on this subject. The most close is this link: Tucker, Compton J.; Grant, Denelle M.; Dykstra, Jon D.
