Tools.
20 production-grade tools your AI agent can call directly against Italian geospatial data — from cross-source POI lookups to H3 aggregation, isochrone proxies, and free-form SQL.
Discovery
| list_sources | List loaded data sources from the catalog with theme/geometry/joinability filters. |
| describe_table | Column-level schema for a qualified table, including data types, comments, and geo-join hints. |
| relationships_graph | Curated table-relationship graph (FK-style edges + georeferences_via). |
Spatial query
| spatial_search | Cross-source POI lookup within a radius around (lat, lon). |
| nearest_n | N nearest POIs to a coordinate, optionally filtered by theme. |
| nearest_geometry | N nearest features from any qualified table (polygons, lines, points). |
| snap_to_geometry | Snap a noisy (lat, lon) to the closest feature in any table within max_dist_m. |
| points_in_polygon | Count + list POIs inside an arbitrary WKT polygon. |
| bbox_of | Geographic extent of any qualified table's geometry column. |
Aggregation
| density_grid | H3 hex aggregation of POIs in a bbox at resolutions 5–10. |
Composite
| site_profile | POI counts + nearest essential services + ISTAT census + OMI real-estate zone, single call. |
| property_neighborhood | Real-estate context: POI counts, nearest POI per theme, earthquake exposure, census section. |
Time series
| time_series_at_point | Aggregate any time-series source within a radius, bucketed by hour/day/week/month/year. |
Geometry primitives
| geometry_ops | PostGIS unary/binary ops on user WKT (buffer, simplify, centroid, envelope, convex_hull, intersection, union, difference). |
| geometry_validate | Validate WKT, return is_valid + reason + fixed_wkt (via ST_MakeValid). |
| coordinate_transform | Reproject WKT between WGS84, Web Mercator, ETRS89, Italy zones, UTM 32/33N. |
| distance_matrix | Geodesic N×N distance matrix between up to 50 input points. |
| isochrone_proxy | Mode-calibrated buffer (walk/bike/drive × minutes) returning a polygon WKT. |
| hex_neighbors | List all H3 cells within ring k of an input cell, with centroids. |
Raw SQL
| query_sql | Free-form read-only SELECT/WITH against the gis database with statement_timeout and auto-LIMIT. |
