+# ADR-002 — PostGIS as Spatial Source of Truth
+
+## Status
+Accepted for V1.
+
+## Context
+GeoIntel stores areas, datasets, AI detections, segmentations, QA geometries, and exports. Spatial operations need to be queryable and persistent.
+
+## Decision
+Use PostgreSQL with PostGIS as the canonical database for:
+
+- project areas,
+- dataset spatial bounds,
+- vector features,
+- detection polygons/boxes,
+- segmentation polygons,
+- QA/QC geometries,
+- spatial metadata,
+- analysis outputs.
+
+Raw rasters, tiles, masks, and large binary artifacts stay on disk/object storage. PostGIS stores metadata and vectorized results.
+
+## Consequences
+The backend can do spatial filtering, intersections, bounding-box queries, and QA matching without reloading every file. The portfolio visibly demonstrates professional GIS database skills.
+
+## Non-goals
+Do not store full large rasters as database blobs in V1.
