Multi-source before model claims
Activity logs, photos, sensors, satellite observations and external records are kept together so every output can be traced back to its evidence source.
Science
Evidence science for fields, forests and land projects.
Terviqa's science layer is built around traceable evidence rather than a single black-box carbon number. The first product packages what can be credibly observed, checked and reviewed today.
- Source provenance from field records and external proof
- Satellite and sensor plausibility checks
- Completeness and risk flags before export
Readiness, not credit issuance
Terviqa separates estimates, completeness checks and certification-support evidence from verified credits or official claims.
Uncertainty is part of the product
Evidence quality, sensor coverage, satellite confidence and missing proof are surfaced as flags instead of hidden behind false precision.
Observable signals
VerdeSat screening metrics help turn landscape condition into reviewable indicators.
Metrics are delivered as AOI-level tables, API/CSV time series and raster chips when needed. They are designed to support reporting, project tracking, habitat planning and compliance review across agricultural and forestry contexts.
Vegetation vigor and stress: NDVI, EVI, SAVI, MSAVI, GNDVI, NDMI and anomaly trends.
Habitat and biodiversity proxies: intactness, Shannon diversity, fragmentation, MSA and B-Score style composites.
Forestry and conservation signals: land-cover change, tree-cover loss, disturbance alerts, canopy-height or biomass screens when available.
Climate and water context: precipitation, temperature, VPD, drought indices and growing-degree-day summaries.
Carbon roadmap
Start with activity-based CO2e and readiness scoring. Add flux-informed indicators after validation matures.
The near-term carbon layer focuses on activity-based CO2e estimates, evidence completeness and methodology-readiness checks. Flux-informed CO2 indicators using EO, weather, FLUXNET Shuttle, ICOS or European flux data and partner field towers are staged as a premium carbon-intelligence layer once validation data is strong enough.
