Application of NPP-VIIRS Satellite in Vegetation Monitoring in Tibet

Based on GIS spatial analysis and mathematical statistical methods, the normalized difference vegetation index (NDVI) of Ritu County in Tibet was retrieved by using TERRA, AQUA and NPP-VIIRS satellite data, and the NDVI retrieval results of different satellite sensors were discussed. The results show that the NDVI value retrieved by the NPP-VIIRS satellite was slightly larger than that of TERRA and AQUA, and the estimated result had a good correlation with the estimated value of the MODIS satellite. Therefore, the NPP-VIIRS satellite can be used in the vegetation growth monitoring of the Tibetan Plateau, and provide richer remote sensing data for the construction of ecological civilization of Tibet.
