PointSav GIS Engine

PointSav GIS Engine

The PointSav GIS Engine is a high-performance, sovereign Location Intelligence platform designed for offline-first, flat-file operation. Built in Rust, it represents a structural departure from traditional, proprietary geographic information systems (GIS) that rely on centralized database instances.

Architectural Principles

The engine is engineered to operate as a stateless application surface, adhering to the PointSav principle of complete data sovereignty.

Flat-File Substrate

Unlike traditional GIS stacks (e.g., PostGIS, Esri) which require persistent database management, the PointSav engine utilizes a flat-file substrate. It consumes geographic data directly from JSONL, GeoParquet, and YAML formats versioned within a Totebox Archive. This architecture ensures the data layer remains entirely decoupled from the application logic, eliminating database maintenance overhead and preventing vendor lock-in.

Sovereign Rendering Stack

The platform avoids commercial SaaS mapping dependencies by utilizing a high-performance, open-source rendering stack:

  • PMTiles: A single-file archive format for tiled data that enables maps to be served directly from standard web servers (Nginx) or blob storage without a dedicated tile server. [pmtiles-spec]
  • MapLibre GL JS: A WebGL-based library for rendering interactive vector maps with high client-side performance. [maplibre-gl-js]
  • Tippecanoe: A tool used to compile massive flat-file datasets into optimized vector tiles, ensuring rapid delivery of complex co-location clusters. [tippecanoe-tool]

Spatial Processing and Orchestration

The engine's core logic resides in the app-orchestration-gis service. This component executes the Woodfine co-location methodology deterministically:

  1. Ingestion: Reads retail and civic infrastructure records from the Totebox Archive.
  2. Analysis: Executes spatial joins and proximity queries to identify co-location clusters across 1.0 km, 3.0 km, and 5.0 km radii.
  3. Ranking: Applies the 12-rank named-anchor matrix to generate site quality tiers.
  4. Serialization: Outputs the processed results as tiled data for the visual interface at gis.woodfinegroup.com.

This stateless approach ensures that the entire GIS environment can be re-provisioned instantly from the immutable data layer, providing maximum service resilience and auditability.
