Evaluation of the Landsat-5 TM and Landsat-7 ETM+ surface reflectance products

Remote Sensing of Environment, 2015
Abstract Maintaining consistent datasets of Surface Reflectance (SR) is an important challenge to ensure long-term quality of Climate Data Records. The Landsat 5 and 7 archives offer a unique data source to monitor globally the land surface at high spatial resolution.

Normalized difference indices in Landsat 5 TM satellite data

Current Developments in Lens Design and Optical Engineering XX, 2019
Urban growth, deforestation, water resources and thawing of the poles due to globe worming are topics of interest in the research community. Normalize difference indices are utilized in remote sensing to analyzed and classify surface cover types. In this paper research, a multispectral satellite data from Landsat 5 TM is preprocessing, in order to ...

Estimating the suspended sediment concentration from TM/Landsat-5 images for the Araguaia River – Brazil

Remote Sensing Letters, 2020
In this study, 68 images from TM/Landsat-5 sensor were used to estimate Suspended Sediment Concentration (SSC) along of the Araguaia River, Brazil. These were combined with in-situ SSC, hydrosedimentometric station (categorical variable), and remote ...

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 ...

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.

Cross-calibration of the Landsat-4 and Landsat-5 thematic mappers

SPIE Proceedings, 2005
The Landsat Thematic Mappers have obtained imagery of the Earth's surface since 1982 with the launch of Landsat 4. However, the absolute calibration of this first instrument, as well as it's cross-calibration to the other two thematic mappers on Landsat 5 and 7, remains in question.

Landsat-5 Thematic Mapper outgassing effects

IEEE Transactions on Geoscience and Remote Sensing, 2004
A periodic 3% to 5% variation in detector response affecting both image and internal calibrator (IC) data has been observed in bands 5 and 7 of the Landsat-5 Thematic Mapper. The source for this variation is thought to be an interference effect due to buildup of an ice-like contaminant film on a ZnSe window, covered with an antireflective coating (ARC),
