ADR-003 — GRB as Authoritative Reference Dataset

Status

Accepted for V1 research and implementation planning.

Context

The Basiskaart Vlaanderen / GRB is a professional Flemish geospatial reference dataset. GeoIntel is scoped to the Kempen, so Flemish official data is highly relevant.

Decision

Treat GRB as the primary QA/QC reference where available. Use it for building/reference geometry validation and later for roads, water, and other base-map objects.

V1 integration strategy:

  1. Implement a GRB provider abstraction.
  2. Start with WFS or downloaded sample/cache depending on practical availability.
  3. Normalize GRB features into a common reference_features model.
  4. Compare AI detections against GRB with IoU/overlap metrics.

Consequences

GeoIntel becomes more relevant to real Flemish GeoAI workflows than a generic OSM-only demo. GRB validation becomes a portfolio killer feature.

Non-goals

Do not block the entire build on live GRB integration. Provide fixtures and provider interfaces first, then connect real GRB when endpoint details are tested.
