How to view a plot’s NDVI
Goal
Review vegetation conditions in a plot using satellite imagery, alongside your field observations.
Steps
Open Precision Agriculture > Dashboard. It shows monitored plots, the average health score and an NDVI ranking to help you decide which plot to review first.
To compare plots, open Image Viewer. Choose the farm, one or more plots and a date, then select the vegetation index: NDVI, EVI, EVI2, NDWI or NRI. The map displays the values across the selected area.
For an individual plot, open Plots, select the plot and choose View NDVI. Review its history, satellite source such as CDSE/Sentinel-2, maximum, mean, median, minimum and standard deviation. Use Synchronize to request a new reading.
Result
A coloured vegetation map with its underlying measurements. Compare capture dates to follow changes; satellite signals need to be checked against conditions in the field.
Common mistakes
- Treating an Outdated reading as current. Check the capture date and synchronize or re-synchronize before drawing conclusions.
- Relying on a heavily clouded capture. Review its cloud percentage and choose a clearer date rather than interpreting cloud interference as a change in the crop.
