Quantifying suspended sediment dynamics in mega deltas using remote sensing data: A case study of the Mekong floodplains
TL;DR: In this article, a Principal Component Analysis (PCA) was applied to obtain uncorrelated reflectance values for five bands of Landsat TM/ETM+ and significant correlations between the scores of the 1st principal component and the values of continuously gauged suspended sediment concentration were shown via high coefficients of determination of sediment rating curves.
Journal ArticleDOI
Early- and in-season crop type mapping without current-year ground truth: Generating labels from historical information via a topology-based approach
TL;DR: In this paper , the authors proposed a new approach that can effectively transfer knowledge about the topology (i.e. relative position) of different crop types in the spectral feature space (e.g. the histogram of SWIR1 vs RDEG1 bands) to generate labels, thereby supporting crop classification in a different year.
Three Decades of Landsat-derived Spring Surface Water Dynamics in an Agricultural Wetland Mosaic; Implications for Migratory Shorebirds
TL;DR: In this article, the authors analyzed water extent dynamics within wetland habitats at a globally important shorebird stopover site for a 1983-2015 Landsat time series, and evaluated the effect of climate on water extent.
Journal ArticleDOI
Comparison of Masking Algorithms for Sentinel-2 Imagery
Viktoria Zekoll,Magdalena Main-Knorn,Jérôme Louis,David Frantz,Rudolf Richter,Bringfried Pflug +5 more
TL;DR: In this article, the performance of the masking provided by Fmask (function of mask) implemented in FORCE, ATCOR (Atmospheric Correction) and Sen2Cor (Sentinel-2 Correction) on a set of 20 Sentinel-2 scenes distributed over the globe covering a wide variety of environments and climates.
Journal ArticleDOI
An Exploration of Terrain Effects on Land Surface Phenology across the Qinghai-Tibet Plateau Using Landsat ETM+ and OLI Data
TL;DR: In this article, the authors detected Normalized Difference Vegetation Index (NDVI)-based land surface phenology metrics at a spatial resolution of 30 m, and explored how LSP varied with topographic factors along a 2600 km belt transect of the central QTP.

A Landsat surface reflectance dataset for North America, 1990-2000
Jeffrey G. Masek,Eric Vermote,Nazmi Saleous,Robert E. Wolfe,Forrest G. Hall,Karl F. Huemmrich,Feng Gao,J. Kutler,Teng-Kui Lim +8 more
TL;DR: Initial comparisons with ground-based optical thickness measurements and simultaneously acquired MODIS imagery indicate comparable uncertainty in Landsat surface reflectance compared to the standard MODIS reflectance product.

Discriminating clear sky from clouds with MODIS
Steven A. Ackerman,Kathleen I. Strabala,W. Paul Menzel,Richard A. Frey,Christopher C. Moeller,Liam E. Gumley +5 more
TL;DR: The MODIS cloud mask algorithm as discussed by the authors uses several cloud detection tests to indicate a level of confidence that the MEDIS is observing clear skies, which is ancillary input to MEDIS land, ocean, and atmosphere science algorithms to suggest processing options.

Calculation of radiative fluxes from the surface to top of atmosphere based on ISCCP and other global data sets: Refinements of the radiative transfer model and the input data
TL;DR: Zhang et al. as discussed by the authors used a more advanced NASA Goddard Institute for Space Studies (GISS) radiative transfer model and improved ISCCP cloud climatology and ancillary data sets.

Spectral signature of alpine snow cover from the Landsat Thematic Mapper.
Jeff Dozier,Jeff Dozier +1 more
TL;DR: In this article, the spectral signatures of the Landsat TM images of the Sierra Nevada were analyzed to distinguish several classes of snow from other surface covers, and a number of TM images were used for automatic analysis of alpine snow cover.
