Landsat spectral index products over Qinghai-Xizang Plateau
Year: 2024
Type: article
Abstract: Remote sensing spectral indices has been widely applied in studies on ecological environment, climate change, etc. over Qinghai-Xizang plateau. Seven widely used remote sensing spectral index products (NDVI, EVI, SAVI, MSAVI, NDMI, NBR, and NDWI) and a unique salinity index (SI) for the Qinghai-Xizang Plateau were generated based on The Landsat BRDF-correction-based surface reflectance products in the Qinghai-Tibet Plateau region. The dataset comprises six periods of remote sensing index products for the years 1990, 2000, 2010, 2015, 2020, and 2022. The results are saved in GeoTIFF format and are accompanied by corresponding quality and metadata files. These products perform better radiometric consistency compared to the spectral index products computed based on surface reflectance products only undergoing atmospheric correction, and has significant application value in various research areas such as quantitative retrieval of remote sensing surface parameters, vegetation monitoring, ecosystem classification, water resource management, fire monitoring, and climate change research in Qinghai-Xizang Plateau.
