Water and terrain context for Thailand agriculture
Explore district terrain, mapped waterways and historical flood observations for agricultural field visits, without claiming crop or rainfall monitoring.
What can geographic data tell an agricultural field team before a visit?
District terrain, mapped rivers and published flood observations can help organize field visits and questions about water access. They cannot establish field-level soil moisture, irrigation reliability, crop health or today's rainfall.
Review workflow
- Bring your own farm boundaries and crop records; do not infer cultivated fields from generic mapped places.
- Group farms by reference district and inspect regional elevation summaries to plan fieldwork at an appropriate scale.
- Inspect mapped waterways and historical observed inundation, recording unmapped channels and observation gaps as unknowns.
- Verify irrigation access, drainage, soil and crop conditions with field staff before using the evidence in an agricultural decision.
What to produce
A district-based field-visit brief with waterway context, historical observations and a checklist for on-farm verification.
| Dataset | Coverage and cadence | Sources and licences | Limitations |
|---|---|---|---|
| Terrain Beta | Thailand district summaries Static historical elevation model Historical or versioned data; no real-time freshness claim | Copernicus DEM GLO-30 via Mapterhorn | District-level elevation summaries sampled from Copernicus DEM GLO-30. They are regional context, not parcel or building elevation and not a flood-probability model. |
| Waterways Beta | Mapped OpenStreetMap coverage in Thailand Versioned releases; no fixed public cadence Historical or versioned data; no real-time freshness claim | Rivers and streams derived from OpenStreetMap. Hydrography completeness varies by area and is not a flood-risk model. | |
| Flood history Beta | Published UNOSAT observation extents in Thailand Fixed historical archive Historical or versioned data; no real-time freshness claim | UNOSAT / United Nations Satellite Centre (Thailand flood extents) | A fixed archive of historical satellite flood-extent observations (UNOSAT). It is not a real-time flood map, and absence of an extent is not evidence that an area stayed dry. |
| Administrative boundaries Stable | Thailand Versioned reference release Historical or versioned data; no real-time freshness claim | Boundaries are the COD-AB reference set for Thailand. They are a cartographic aid, not a legal or cadastral boundary. |
Questions this data cannot answer
This release has no field-level crop, yield, soil-moisture, rainfall or drought-index feed. Bangkok monitoring-station metadata does not provide readings or nationwide irrigation coverage.

Prepare a pilot with your team
For a fieldwork pilot, define farm boundaries, reporting period and water-access questions. Review district-match coverage and field observations together; agree which gaps require a survey or a new data source.
