Verdi Dashboard provides satellite-determined relative Normalized Difference Vegetation Index (NDVI) visualization for your Areas of Interest (AOIs). NDVI is a widely used vegetation health metric derived from aerial imagery. Typically, NDVI imagery for your AOIs will be available within 24 hours after creation.
What is NDVI?
NDVI quantifies vegetation greenness by analyzing how plants reflect near-infrared (NIR) and red light. Healthy vegetation absorbs red light and reflects NIR, while stressed or sparse vegetation reflects more red light. The NDVI value ranges from 0 to 1, where:
Close to 1 (blue/green) → Dense, healthy vegetation
Close to 0 (red/yellow) → Little to no plant growth
0 → Water, bare soil, or non-vegetated surfaces
By continuously monitoring NDVI over time, growers can assess plant health, detect stress, and optimize management practices.
Relative NDVI vs. Absolute NDVI
Verdi Dashboard offers relative NDVI visualization.
Relative NDVI normalizes NDVI values within each AOI, adjusting the scale based on local vegetation conditions. This enhances contrast, making it easier to spot variations within a field rather than the application of comparing different locations or seasons. Absolute NDVI, on the other hand, provides raw, calibrated values ranging from -1 to 1, which is useful for scientific comparisons but requires advanced calibration that the Verdi Dashboard does not currently support.
Relative NDVI is particularly useful for precision agriculture because it helps identify relative differences in plant vigor within the same field, highlighting problem areas that might require further investigation or targeted interventions.
Applications
NDVI visualization is widely used in vineyards and orchards to:
Monitor canopy health – Detect stressed areas early to optimize irrigation and nutrient management.
Assess uniformity – Identify uneven growth patterns that might indicate soil variability, disease, or irrigation issues.
Guide precision agriculture practices – Adjust inputs such as fertilizer or water based on NDVI-derived plant vigor maps.
Improve harvest planning – Track growth cycles and ensure optimal picking times by monitoring vegetation trends.
