Because it has: Evapotranspiration
- 02
Water accounting
Track how much water crops actually consume across a command area.
- 03
Drought indices
Track SPI and SPEI style indices for declarations and relief.
Because it has: Drought Indices
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.
