Endpoint Reference

Method	Endpoint Pattern	Description & Specs
GET	/vector_tiles/tiles/<table>/<z>/<x>/<y>.pbf	Dynamic PostGIS vector tiles via `ST_AsMVT` & `ST_TileEnvelope`. EPSG:3857 · Local disk cached · Atomic file lock
GET	/vector_tiles/api/tables/?search=<aoi>	Introspects registered tables in `geometry_columns` and returns layer bounds. JSON · Filters out raster footprints
GET	/vector_tiles/api/activation/<code>/aoi/<num>/vector-layers/	GeoServer layer groups, WMS, WFS, and GWC WMTS/TMS vector tile URLs for a single AOI. REST JSON · Includes bounding box
GET	/vector_tiles/api/activation/<code>/vector-layers/	Published layer groups across all AOIs within a CEMS activation. REST JSON · Whole activation view
GET	/vector_tiles/api/tables/<table>/distinct/<col>/	Unique column values for client-side styling, choropleth breaks, and legend generation. JSON · Queries attribute table directly
GET	/vector_tiles/api/geojson/?table=<table>&bbox=...	Spatial query returning standard GeoJSON FeatureCollections for non-tiled workflows. WGS84 · Max 5,000 features

Caching: Vector tiles are computed directly in PostgreSQL and saved to disk at static_tiles/<table>/<z>/<x>/<y>.pbf. Repeated client requests bypass the database and are served directly by the web server.
