# Theater-to-Person Predictive Scale
**Entity class:** Multiscale modeling concept
## Definition
**Theater-to-person predictive scale** describes the transition from an area-level physical field to estimates at a particular asset, location, route, or human receptor. It requires sufficient spatial and temporal resolution plus a receptor model, trajectory or location, shielding, response characteristics, and validation.
The field does not become individualized merely because it is computed quickly. Person-scale use is a downstream coupling problem.
