SansonOpen Source Geospatial Server

OGC API Features compliant — powered by PostgreSQL + PostGIS

OGC API Features

Native compatibility with QGIS, ArcGIS, FME, and any OGC-compliant client. No plugin or special configuration needed.

Filter features by attributes and geometry using the OGC CQL2 Text standard — comparison, logic, text, spatial operators.

Background GeoJSON import with progress tracking, batch inserts, and structured logs. Supports gzip-compressed files.

Mapbox Vector Tiles via PostGIS ST_AsMVT. Compatible with MapLibre GL JS, Leaflet, and QGIS.

Dashboard, workspace and collection management, interactive map and table views, data import with live progress, API explorer.

Zero extra infrastructure. PostgreSQL handles data, spatial queries, and the job queue (pg-boss). No Redis, no RabbitMQ.

Named after Nicolas Sanson (1600--1667), father of French cartography and royal geographer to Louis XIII and Louis XIV.
