What you can do with it
Typical work that data of this type supports.
- 01
Irrigation scheduling
Decide when and how much to irrigate.
Because it has: Irrigated area
- 02
Water accounting
Track how much water crops actually consume across a command area.
- 03
No-gauge areas
Monitor places with no ground stations.
Because it has: Remote sensing
Where AI adds value
Ideas for machine learning and AI agents built on this kind of data.
- 01
Field-scale ET
Estimate crop water use per field by combining satellite and weather with ML.
- 02
Demand forecasts
Predict irrigation demand weeks ahead for canal and pump planning.
- 03
Segmentation
Map water, crops and land use pixel by pixel with deep learning.
