# PostGIS spatial stack for the trip planner.

#   docker-compose up -d postgis     # start the DB (schema.sql runs on first boot)
#   ./import.sh ~/trips/osm/nh.osm.pbf nh   # import an OSM extract (one-shot osm2pgsql)
#   docker-compose up -d spatiald    # start the query service on :5005
#
# Composed for docker-compose v1 (3.8) AND v2 (the same file works with
# `docker compose` once the v2 plugin is available): no healthchecks or
# `depends_on` conditions — import.sh polls pg_isready itself, and spatiald
# tolerates a not-yet-ready DB at boot.
#
# OSM_DIR (default ~/trips/osm) is where the PBF extracts live — outside the
# dev tree. Export it to override.
