Ground evidence
FieldTrace observations, inspections, photos, measurements and operator records.
FieldTraceEnvironmental evidence · Fourth evidence pillar
Earth Observation, geospatial data and FieldTrace ground truth are linked to farms, plots, batches, routes, buyer regions, contracts and funding pathways — without transferring institutional decision authority.
Spatial intelligence completes the evidence architecture. It does not replace field, economic or institutional evidence.
FieldTrace observations, inspections, photos, measurements and operator records.
FieldTraceListings, volumes, prices, batches, facilities and route activity.
MarketplacesAuthority profiles, reviewer routes, reliance conditions and controlled releases.
Governance SpineHazard, exposure, vulnerability, trend, uncertainty and spatial provenance.
Spatial IntelligenceIllustrative profiles for the Nigeria and Netherlands market environments.
Farm and logistics-route exposure
Short-term signals and long-term trends
Operational support, not dispatch authority
Observed, modelled and proxy evidence remain visibly separated.

| Soil-moisture observation | FieldTrace | Plot NGA-BEN-014-P2 | Observed | Accepted |
| Flood-recurrence layer | Historical model | Route NGA-RTE-022 | Proxy | Held |
| Erosion inspection | FieldTrace | Farm NGA-BEN-014 | Observed | Accepted |

Spatial evidence may contextualise soil condition, vegetation trend, water stress and land-management history within the Nigeria pilot.
Subject, geometry, intended use, source class and prohibited reliance.
Completeness, temporal fit, uncertainty and ground-truth sufficiency.
Farm, plot, batch, route, contract, region and actor linkage.
HEV logic, weights, thresholds and limitations.
Permitted use for procurement, logistics, finance or insurance.
Exceptions, reliance conditions and unresolved evidence gaps.
Bounded output, authorised recipient, version and audit continuity.
Regional exposure, route bundling, buyer-region risk and continuity evidence.
Soil health, hazard exposure, regenerative evidence and carbon context.
Inspections, calibration events, observations and discrepancy escalation.
Risk adjustment, reliance conditions, adaptation actions and DFI evidence packs.
