Normalized Difference Vegetation Index (NDVI) results of the five center pivots analysed: pivot 1 (A), pivot 2 (B), pivot 3 (C), pivot 4 (D) and pivot 5 (E)
Leaves with low N accumulation, and consequently lower chlorophyll content have higher reflectance in the visible region of the electromagnetic spectrum (400-700nm) and low reflectance in the near-infrared region (DIACONO et al., 2013; SINGH et al., 2017), causing a decrease in the
Normalized difference vegetation index (NDVI).
The NIR light camera allowed the creation of
normalized difference vegetation index maps of the vineyard that identified areas of variability less visible with standard photography.
Using satellite bands indicated in Table 1, we calculated the
Normalized Difference Vegetation Index (NDVI), which highlights vegetation, and the Normalized Difference Building Index (NDBI), which highlights building.
This paper tried to employ a quantitative approach to track the relationship between SHI and common land cover indices and select proper indices, including the
Normalized Difference Vegetation Index (NDVI) (Kriegler et al.
The supported near-infrared sensors from Sentera, including the High-Precision NDVI Single sensor and the Sentera Double 4K, allow growers to create NDVI (
normalized difference vegetation index) maps to accurately detect crop stress.
The snapshot showed that the mining site has 'lower
normalized difference vegetation index,' a measure for estimating vegetation health and density.
