Location due diligence for bank collateral in Thailand
Organize geographic evidence for collateral review using Thailand boundaries, place context, flood history and district elevation summaries.
What geographic evidence should accompany a collateral inspection?
Create a location dossier that separates address matching, district context and historical flood observations from the bank's valuation and credit decisions. MapScale provides reference evidence; an appraiser still verifies the parcel and property.
Review workflow
- Match the borrower-supplied address to coordinates, recording uncertainty instead of silently accepting the first place result.
- Attach the reference administrative area using stable identifiers; do not treat its boundary as the title-deed boundary.
- Inspect historical flood observations and district elevation summaries, keeping regional terrain separate from the property's surveyed elevation.
- Give the dossier to the appraiser together with missing coverage and the documents requiring on-site verification.
What to produce
A collateral inspection dossier with coordinates, administrative reference, observation sources and unresolved verification tasks.
| Dataset | Coverage and cadence | Sources and licences | Limitations |
|---|---|---|---|
| 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. |
| 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. |
| 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. | |
| Place search Stable | Thailand Versioned releases; no fixed public cadence Historical or versioned data; no real-time freshness claim | Places derive from OpenStreetMap and vary in completeness by area. Treat names as display data and join on stable ids. |
Questions this data cannot answer
No live government land appraisal feed, market valuation, title-deed verification, ownership record or credit score is provided by this catalog. Do not infer a lending decision from regional geography.

Prepare a pilot with your team
For a collateral pilot, choose a small sample of verified locations and the inspection questions your appraiser needs answered. Agree acceptable address-match uncertainty and list documents that geography cannot verify.
