Stable public map
Working controls, mobile presentation, declared scope, governed delivery and meaningful fallback information.
AP Institute Standard / 2026.1
Every map states what is known, when it is valid, and how precisely it can be placed.
The AP atlas system separates source evidence, contextual geography, analytical reconstruction and editorial interpretation. Public versions describe verified product maturity rather than visual iteration.
Source-linked atlas
Permanent records, citations, confidence, source profiles and reviewable geography.
Analytical atlas
Temporal controls, analytical layers and explicit separation of events, context and reconstruction.
Integrated system
Rust and PostGIS delivery, high-volume performance, export and cross-atlas governance.
Institute flagship
End-to-end provenance, precision, temporal validity, monitoring and versioned release manifests.
Highest current profile
The complete AP public-release standard for live and research atlas systems.
Geographic precision
A visible point is not automatically an exact location.
ExactSource-supported site or event coordinate.
LocalityTown, settlement or named-place coordinate.
RegionalAdministrative or regional location.
ProxyExplicit contextual anchor, never treated as an exact site.
Universal quality gates
Every release must remain readable, attributable and temporally honest.
Provenance
Each promoted record retains a source profile or governed source class.
Validity
Dates, intervals and undated context are represented as different states.
Precision
Exact, locality, regional and proxy geometries cannot be visually conflated.
Accessibility
Desktop, mobile and PWA views preserve controls, legends and selected records.
Rust delivery
Public data passes through the governed Rust atlas interface.
Traceability
Versions, record counts and quality gates are stored in public manifests.
