Landsat 5/Landsat 7 underfly cross-calibration experiment

SPIE Proceedings, 2000
There was a one-time opportunity to obtain nearly coincident coverage from both Landsat 5 and Landsat 7 as Landsat 7 drifted to its final orbital position during the initialization and verification phase following launch. During the underfly period, Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data were collected using the U.S Landsat 7 ground ...

The study of instruments and assessment tools in Canopy cover using temporal satellite data is the subject of intense research interest worldwide. The protection and control of environmental resources, namely forests and also their rational management, could contribute significantly to reducing the greenhouse effect, the lowering of flood phenomena and

Landsat-7 and Landsat-5 thermal band calibration updates

SPIE Proceedings, 2009
ABSTRACT Landsat-7 ETM+, launched in April 1999, and Landsat-5 TM, launched in 1984, both have a single thermal band. Both instruments’ thermal band calibrations have been updated: ETM+ in 2001 for a pre-launch calibration error and TM in 2007 for data acquired since the current era of vicarious ca libration has been in place (1999) .

Radiometric calibration status of Landsat-7 and Landsat-5

SPIE Proceedings, 2007
Launched in April 1999, Landsat-7 ETM+ continues to acquire data globally. The Scan Line Corrector in failure in 2003 has affected ground coverage and the recent switch to Bumper Mode operations in April 2007 has degraded the internal geometric accuracy of the data, but the radiometry has been unaffected.
