Digital Farm Twin
The digital farm twin is the canonical object at the centre of the platform. It is the virtual representation of all physical and operational entities of a farm — and the contract the four APIs cooperate around.
Entities
| Entity | Source API |
|---|---|
| Organisation | Farm |
| Farm | Farm |
| Field | Farm |
| Region (ROI) | Farm |
| Sensor & Datastream | Sensor Things |
| Map & Layer | Spatio-Temporal |
| Activity | Activity |
| Service & Result | Service Registry |
Properties
- Spatial. Every locatable entity carries a GeoJSON geometry or a STA Location.
- Temporal. Every observation, activity and layer carries a timestamp; history is queryable.
- Semantic. Entities can be tagged with AgroVoc concepts for cross-language and cross-platform interpretability.
- Relational. Every record links back to its parents and to the records of other APIs (e.g. an Activity references a Field, the Sensors used and the Layers produced).
