What you can do with it
Typical work that data of this type supports.
- 01
No-gauge areas
Monitor places with no ground stations.
Because it has: GRACE
- 02
Long records
Use consistent records going back decades.
- 03
Trend hotspots
Find where water tables are falling year after year.
Because it has: Groundwater Storage Anomaly
Where AI adds value
Ideas for machine learning and AI agents built on this kind of data.
- 01
Segmentation
Map water, crops and land use pixel by pixel with deep learning.
- 02
Data fusion
Blend satellite and ground data into one better estimate.
- 03
Gap filling
Rebuild missing well readings from neighbours, rainfall and season.
