Radiometric saturation of Landsat-7 ETM+ data over the Negev Desert (Israel): problems and solutions

Landsat-7 ETM+ Radiometric Stability and Absolute Calibration

Launched in April 1999, the Landsat-7 ETM+ instrument is in its fourth year of operation. The quality of the acquired calibrated imagery continues to be high, especially with respect to its three most important radiometric performance parameters: reflective band instrument stability to better than ±1%, reflective band absolute calibration to better than ±5%, and thermal band absolute calibratio...

Radiometric Normalization of Landsat Etm+ Data for Multitemporal Analysis

The advantages of Remote Sensing for the knowledge of environmental dynamics are widely ascertained by scientific community. Spatial synchronization and temporal resolution of large areas have meaningfully improved quantity and quality of satellite imagery which have assumed an important role in the field of environmental monitoring. Nevertheless, preliminary processing problems of multitempora...

Radiometric cross-calibration of the Landsat-7 ETM+ and Landsat-5 TM sensors based on tandem data sets

Early in its mission, the Landsat-7 spacecraft was temporarily placed in a ‘‘tandem’’ orbit very close to that of the Landsat-5 spacecraft in order to facilitate the establishment of sensor calibration continuity between the Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Landsat-5 Thematic Mapper (TM) sensors. The key period for the tandem configuration was June 1–4, 1999, during which hund...

Assessment of the Short-term Radiometric Stability between Terra MODIS and Landsat 7 ETM+ Sensors

Absolute radiometric calibration of Landsat 7 ETM+ using the reflectance-based method

A key to the continuation of quantitative data from the Landsat series of sensors is the radiometric understanding of the sensor. Vicarious calibration methods are one approach that has been used successfully for the absolute radiometric calibration of Thematic Mapper (TM). One of these vicarious methods is the reflectance-based approach that is applied here to the radiometric calibration of th...
