Europe-plus Evidence Surface Map Publication Contract¶
Europe-plus is a governed regional filter view. It keeps only Europe-plus countries from the broader publication surface and still withholds Nordic-only overlays that would overstate regional context coverage.
Engine Decision¶
One shared map document engine serves every published scope. Scope differences must be encoded in governed bounds, layer eligibility, default basemap, and reader caveats rather than hidden in separate renderer forks.
Scope Posture¶
- Scope key:
europe_plus - Scope kind:
region - Parent scope:
world - Default basemap:
light - Default distance circle diameter:
30 km
The opening extent centers the European frame while keeping enough margin for future expansion into non-Nordic Europe-plus countries.

Filter Surfaces¶
- Country filters
- Layer toggles
- Search
- Time window
- Distance circles
- Basemap switch
Legend Sections¶
- Human evidence markers
- Animal evidence markers when present
- Context overlay symbols
- Density ramp when archaeology density is visible
Caveats¶
- Europe-plus is derived from the world publication surface by governed country filtering, not by a second evidence pipeline.
- Nordic-only pollen, archaeology, and fieldwork overlays remain absent here on purpose.
- Future non-Nordic Europe-plus additions should arrive by country onboarding, not by custom one-off bundle logic.
