Tracking Landsat-5 by a differential GPS technique

Astrodynamics Conference, 1986
As part of an international campaign to develop precise geodetic applications of the Global Positioning System (GPS), the Jet Propulsion Laboratory is conducting a demonstration of differential GPS tracking using Landsat-5. Two strategies have been investigated: one in which only the Landsat-5 orbit is estimated, and one in which both the Landsat-5 and

Landsat-5 Thematic Mapper reflective-band radiometric stability

IEEE Transactions on Geoscience and Remote Sensing, 2004
Four aspects of the radiometry of the Landsat-5 Thematic Mapper were characterized over the 20+ year mission lifetime for the six reflective bands: relative gain (the radiometric gain of each detector within a band relative to other detectors in that band), bias, performance of the Internal Calibrator (IC) system, and noise.

Landsat-5 TM reflective-band absolute radiometric calibration

IEEE Transactions on Geoscience and Remote Sensing, 2004
The Landsat-5 Thematic Mapper (TM) sensor provides the longest running continuous dataset of moderate spatial resolution remote sensing imagery, dating back to its launch in March 1984. Historically, the radiometric calibration procedure for this imagery used the instrument's response to the Internal Calibrator (IC) on a scene-by-scene basis to ...

Cross-calibration of Landsat 5 TM and Landsat 8 OLI with Aqua MODIS using PICS

SPIE Proceedings, 2014
The Thematic Mapper (TM) onboard the Landsat 5 (L5) has provided an unprecedented amount of earth observations for more than 25 years since its launch on March 1, 1984. The MODIS sensor onboard the Aqua satellite is a part of the afternoon constellation of spacecraft and has been successfully providing near-continuous observations of the earth’s ...

Landsat-5 TM and Landsat-7 ETM+ absolute radiometric calibration using the reflectance-based method

IEEE Transactions on Geoscience and Remote Sensing, 2004
The reflectance-based method of vicarious calibration has been used for the absolute radiometric calibration of the Landsat series of sensors since the launch of Landsat-4. The reflectance-based method relies on ground-based measurements of the surface reflectance and atmospheric conditions at a selected test site nearly coincident with the imaging of ...

Grossflächige Landnutzungsbestimmung Aus Landsat-5-TM-Daten

1989
Es wird uber eine experimentelle Auswertung von Landsat-5-TM-Daten be­richtet. Ziel dieser Arbeit war es, mit einem Ansatz fur ein groseres Gebiet Landnutzungsarten gleichzeitig zu bestimmenen. Die Nutzungsar­ten sollten aus dem Reflexionsverhalten in ubergeordneten und jahres­zeitlich unveranderlichen Klassen festgelegt werden.

A refined empirical line approach for reflectance factor retrieval from Landsat-5 TM and Landsat-7 ETM+

Remote Sensing of Environment, 2001
The recent launch of Landsat-7 ETM+ extends the uninterrupted stream of TM and ETM+ images to a potential span of 32 years. This exceptional image set will allow long-term studies of natural resources, but will require an operational method for converting image digital number (dn) to the temporally comparable surface reflectance factor (rsl).

Landsat-7 ETM+ and Landsat-5 TM Cross-Calibration Based on Tandem Data Sets

2000
Early in its mission, the Landsat-7 spacecraft was temporarily in a tandemorbit that drifted across that of the Landsat-5 spacecraft in order to facilitate sensor cross-calibration based on nearly-coincident scenes acquired by the Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Landsat-5 Thematic Mapper (TM).

Prediction and validation of foliage projective cover from Landsat-5 TM and Landsat-7 ETM+ imagery

Journal of Applied Remote Sensing, 2009
The detection of long term trends in woody vegetation in Queensland, Australia, from the Landsat-5 TM and Landsat-7 ETM+ sensors requires the automated prediction of overstorey foliage projective cover (FPC) from a large volume of Landsat imagery. This paper presents a comparison of parametric (Multiple Linear Regression, Generalized Linear Models) and

Radiometric recalibration procedure for landsat-5 thematic mapper data

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
The landsat-5 (L5) satellite was launched on March 01, 1984, with a design life of three years. Incredibly, the L5 thematic mapper (TM) has collected data for 23 years. Over this time, the detectors have aged, and its radiometric characteristics have changed since launch. The calibration procedures and parameters have also changed with time.
