Source profileThis atlas separates overview geometry, source-registered points, digitized front geometry, historical boundaries, and bibliographic evidence. Each record carries source, confidence, geometry, and provenance metadata. Mass event layerv0.8 adds 3,020 event-index nodes and 170 density cells. They are structured event-index records for spatial reading; use Event density for overview and Event index for lazy-loaded year/theater chunks.
Map view disciplineDefault Operational view keeps the map readable while retaining historical boundaries and selected operational records. Use Control state, Operation zones, Source density, or Source points for focused layer inspection.
Source chunkingSource metadata is split into year, theater, and source-id chunks so large evidence layers can be loaded without slowing the operational map.
Lazy loading is activeChoose Layer: Source points to inspect registered bibliography and evidence locations for the selected year or theater. Use Source density for a fast spatial overview.
Source density policyv0.6 adds source chunking by year, theater, and source id. Source points show where source material exists; they are not event claims. The map now renders density first and lazy-loads source-point chunks by selected theater or year only when Source points are requested.
Digitization methodThe digitization method separates overview front geometry, archival reference lines, and digitized front traces. Each front layer is presented with its date, source path, geometry class, and provenance status so the operational view remains distinguishable from the evidentiary source layer.

Version and limitsThis is a source-aware historical GIS interface for the First World War. The atlas distinguishes registered operational records, historical boundary context, overview front geometry, digitized front references, source materials, and analytical timeline layers so each visual element can be read by provenance and geometry class.
