Using a NIR (Near Infrared) camera, NDVI agriculture maps provide farmers with detailed data about their crops. NDVI highlights areas of irregularity that may not be visible to the human eye. Some of these irregularities may be due to poor nutrient supply, irrigation issues, bugs and pests, or physical damage caused by weather. Identifying these issues quickly allows for farmers to implement immediate changes to resolve the problem. NDVI maps are a low cost solution that can raise yields and increase profit.
UAVs allows for a level of detail that is unprecedented for farming, allowing in precision agriculture. NDVI maps allow for even the smallest problem areas to be identified, measured, and documented.
This map illustrates a 0.07 hectare area (~35m by ~20m) that was recognized from the data as being problematic. Upon ground truthing by the farmer, an area of small weeds was found out competing the Cranberry crop. The farmer applied the necessary pesticide immediately and the problem was resolved by the next flight a month later.
Increased recognition of issues
Near infrared cameras can pick up details invisible to the naked eye. Issues can be dealt with before they result in irreversible damage. In the photos below, an irregularity was noticed in a vineyard through the NDVI map. Upon closer inspection, the farmer realized that an irrigation hose had clogged and was not spreading water (lower middle of map). A quick fix on the hose allowed the water to be restored. However, this would not have been noticed by the naked eye until the grapevines were close to mortality.
- Cost effective solution to manned aircraft
- Issues are accurately and easily mapped
- Imagery can be compared to future imagery to gauge success of treatments
- Reduces the amount of time spent in the fields
- Can be used for insurance documentation
