How to Monitor Crops Using Satellite Imagery
Satellite imagery lets you see crop health across an entire field without walking it. Here's how NDVI works and how Hekitari turns it into action.
Farmers monitor crops using satellite imagery by tracking vegetation health (NDVI) over time, which reveals crop vigour and stress across a whole field without walking every metre. Hekitari does this automatically on the farmer's exact UPI parcel and presents it as a simple colour map.
What is NDVI and what does it show?
NDVI (the Normalised Difference Vegetation Index) measures how vigorously plants are growing by comparing the light they reflect. In practical terms, Hekitari turns it into a colour map of your field: healthier areas and stressed areas stand out at a glance, so you know where to look before damage is visible to the eye.
How do you act on the data?
- Receive alerts for crop stress, waterlogging, and drought.
- Check a daily field-health summary and a historical view across the season.
- Monitoring is passive — no action is needed to receive updates.
