Evaluation of MODIS-Landsat and AVHRR-Landsat NDVI data fusion using a single pair base reference image: a case study in a tropical upstream catchment on Java, Indonesia

open access: yesInternational Journal of Digital Earth, 2022
Image blending is one of the alternative methods to fill temporal gaps in the monitoring of historical vegetation properties using continuous NDVI derived from Landsat 5 TM / 7 ETM+ and 8 OLI images.

Normalized Difference Vegetation Index Continuity of the Landsat 4-5 MSS and TM: Investigations Based on Simulation

open access: yesRemote Sensing, 2019
Landsat 4-5, built at the same time and with the same design, carrying the Multispectral Scanner System (MSS) and the Thematic Mapper (TM) simultaneously, jointly provided observation service for about 30 years (1982−2013).

LANDSAT TM imagery for alteration identification

open access: yes, 1994
LANDSAT Thematic Mapper (TM) data can be used to map altered rocks given the right geological environment. This paper briefly reviews spectral reflectance theory as it applies to the detection of different minerals and presents an example of how this theory can be applied to LANDSAT TM data.

Unmixing-Based Landsat TM and MERIS FR Data Fusion

open access: yesIEEE Geoscience and Remote Sensing Letters, 2008
An unmixing-based data fusion technique is used to generate images that have the spatial resolution of Landsat Thematic Mapper (TM) and the spectral resolution provided by the Medium Resolution Imaging Spectrometer (MERIS) sensor. The method requires the optimization of the following two parameters: the number of classes used to classify the TMimage ...
