Nordic Evidence Atlas Map Publication Contract

Nordic is the regional detail surface. It keeps the shared human and animal evidence layers, then adds Nordic-only environmental, archaeology, boundary, and fieldwork overlays that remain interpretable at this scale.

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: nordic
  • Scope kind: region
  • Parent scope: europe_plus
  • Default basemap: voyager
  • Default distance circle diameter: 20 km

The opening extent stays tight on Nordic countries so lake, site, and archaeology context reads as map content rather than background noise.

Filter Surfaces

  • Country filters
  • Layer toggles
  • Search
  • Time window
  • Distance circles
  • Basemap switch
  • Animal species focus when animal layers are present
  • Animal scope when animal layers are present
  • Animal coordinate confidence when animal layers are present
  • Animal temporal windows when animal layers are present
  • Nordic animal leads only when animal layers are present

Legend Sections

  • Human evidence markers
  • Animal evidence markers when present
  • Context overlay symbols
  • Density ramp when archaeology density is visible
  • Nordic environmental context markers
  • Nordic boundary and archaeology overlays
  • Fieldwork documentation marker when checked-in gallery media is present

Caveats

  • Nordic-specific overlays describe the current Nordic recovery slice and must not be generalized outward.
  • Animal points can remain visible even when their Nordic relevance is regional rather than one exact country.
  • Approximate or inferred coordinates remain visible with explicit warnings instead of being silently dropped.
