Cropwise Imagery has multiple vegetation indexes available to visualize plant health across all crop growth stages and agronomic scenarios. This includes NDVI (Red), NDVI Variability, and Visual.
Vegetation Index |
Vegetation Index Description |
|---|---|
| NDVI (Red) | The Normalized Difference Vegetation Index (Red) is the most common index used to measure plant health. The amount of light that is absorbed by the plant is measured from -1 to +1. Non-vegetative objects like roads are calculated in the -1 to 0 range while vegetation is seen in the 0 to +1 range, with 0 being unhealthy and +1 being very healthy. |
| NDVI Variability | The NDVI Variability Index uses standard deviation to quantify field variability. This index can help identify fields with potential problems during the seasons (anomalies appearing, diseases spreading, or any other issues) and also make informed decisions regarding precision management practices. A field with high variability might benefit from targeted and differentiated management practices. |
| Visual | Visual, also known as RGB, is what we would see as humans looking down from space. You can use this view when you want to check for clouds or other atmospheric anomalies on your images. |
There are four additional indexes that can be enabled, upon request, to unlock deeper field insights through detecting water stress, flooding risk, and nutrient deficiencies on a field.
Vegetation Index |
Vegetation Index Description |
|---|---|
| SAVI | The Soil Adjusted Vegetation Index (referred to as SAVI) takes into account bare soil alongside the plants that also reflects light. This index is a good choice for early-stage plants or crops that do not yet have complete canopy closure. |
| NDWI | The Normalized Difference Water Index is used to detect standing water across fields, which is ideal for assessing flood impact after heavy rain and evaluating replant decisions during wet seasons. |
| NDMI (Sentinel Images Only) | The Normalized Difference Moisture Index is useful for detecting early crop water stress, monitoring crop condition during dry periods, or even supporting yield risk decisions. |
| LCI | The Leaf Chlorophyll Index measures chlorophyll content in vegetation, directly linked to plant vigor and nitrogen status, so agronomists can evaluate fertilizer application efficacy and identify nutrient deficiencies before they affect yield. |
