Science
Earth observation
Earth-observation products provide regional context where direct groundwater observations are sparse.
Scientific question
Which remotely sensed indicators add defensible information about recharge context, terrain, drainage and structural controls?
Methods and evidence
Use versioned terrain, land-cover, hydrography and structural/context layers with documented resolution, date and processing history.
Expected scientific outputs
- Terrain context
- Land-cover context
- Surface-water context
- Structural/context layers
Limits and safeguards
Remote-sensing proxies do not directly observe groundwater. Scale mismatch and proxy uncertainty must remain visible.
