NDVI Sample Clauses

NDVI. The Normalized Differentiated Vegetation Index (NDVI) is defined as (NIR-red)/(NIR+red). For Landsat 8 this means in band numbers: (B5-B4)/(B5+B4). The employed processing chain at DLR first calculates a cloud mask for each image using Fmask (▇▇▇ et al. 2015). Subsequently, NDVI is calculated. The resulting NDVI maps are masked according to the cloud mask, clipped to the study areas and resampled to the 100 m grid. The accuracy of the NDVI map depends on the radiometric quality of the input data. However, discontinuous data availability due to cloud cover has a larger influence on the quality of this product.
