TL;DR: Landsat 8, a NASA and USGS collaboration, acquires global moderate-resolution measurements of the Earth's terrestrial and polar regions in the visible, near-infrared, short wave, and thermal infrared as mentioned in this paper.
Journal ArticleDOI
Characterization of Landsat-7 to Landsat-8 reflective wavelength and normalized difference vegetation index continuity
TL;DR: In this paper, the authors compared the top of atmosphere (TOA) and atmospherically corrected surface reflectance for the spectrally corresponding visible, near infrared and shortwave infrared bands, and derived normalized difference vegetation index (NDVI), are compared and their differences quantified.
Journal ArticleDOI
Web-enabled Landsat Data (WELD): Landsat ETM+ composited mosaics of the conterminous United States
David P. Roy,Junchang Ju,Kristi Kline,Pasquale L. Scaramuzza,V. Kovalskyy,Matthew C. Hansen,Thomas R. Loveland,Eric Vermote,Chunsun Zhang +8 more
TL;DR: In this paper, temporally composited, mosaics of the conterminous United States (CONUS) were generated on a monthly, seasonal, and annual basis using 6521 ETM+ acquisitions from December 2007 to November 2008.
Journal ArticleDOI
A general method to normalize Landsat reflectance data to nadir BRDF adjusted reflectance
David P. Roy,Hankui K. Zhang,Junchang Ju,Junchang Ju,Jose Gomez-Dans,Philip Lewis,Crystal B. Schaaf,Qingsong Sun,Jian Li,Haiyan Huang,V. Kovalskyy +10 more
TL;DR: In this paper, a generalized approach is developed to provide consistent view angle corrections across the Landsat archive, which is not applicable for generation of Landsat surface albedo, which requires a full characterization of the surface bidirectional reflectance distribution function (BRDF), or for correction to a constant solar illumination angle across a wide range of sun angles.
Journal ArticleDOI
Continental-scale Validation of MODIS-based and LEDAPS Landsat ETM+ Atmospheric Correction Methods
TL;DR: In this article, the accuracy of two Landsat atmospheric correction methods, a MODIS-based method and the Landsat Ecosystem Disturbance Adaptive ProcessingSystem (LEDAPS) method, is compared.
