H1DR4 Research converts the indexed public crime surface into comparative statistics, category pressure, area deltas, timelines, and reproducible map views.

## Coverage

The current street-level layer includes official public records from UK Police, NYPD, Chicago Police, Los Angeles public crime data, and Washington, D.C. public crime incidents. The wider reference index includes official wanted-person and sanctions sources.

## Analysis

- Compare geographic areas and time windows.
- Inspect category shares and severe-event pressure.
- Move through daily or monthly timelines.
- Switch between aggregate density and individual incidents.
- Open the underlying event or dossier when a public source record exists.

## Agent access

Use H1DR4 MCP tools `h1dr4_area_risk` and `h1dr4_compare_areas` for supported coordinates. Results are descriptive public-data analysis, not a guarantee of safety or a prediction of a specific event.
