The FOSS4G stack we build with
Free and open source software for geospatial: mature, standards-based and used in production worldwide. We pick the right tool for the job and we run all of them ourselves.
Databases and data formats
- PostgreSQL + PostGIS
PostGIS
The standard open source spatial database. Geometry, geography, raster, topology and thousands of spatial functions, with the reliability of PostgreSQL. The heart of our systems.
- Routing
pgRouting
Shortest path, network analysis and routing directly in the database. Useful for road, utility and telecom networks.
- GDAL / OGR
GDAL / OGR
The universal translator for raster and vector formats and coordinate transformations. The backbone of our ETL pipelines.
- Cloud-native
GeoPackage · GeoParquet · COG · PMTiles
Modern, open formats for exchange and cloud storage: simple files, fast partial reads, no server needed.
Map servers and tile services
- OGC WMS · WFS · WMTS
GeoServer
Full-featured Java map and feature server with styling, security and clustering. Our choice for standards-heavy, enterprise setups.
- OGC WMS · WFS
MapServer
A fast, lightweight C-based map server with a very long track record.
- Tile cache
MapProxy
Caches and reprojects tiles from upstream services, taking load off backends and making maps fast.
- Vector tiles
Martin · pg_tileserv · Tippecanoe
Vector tiles straight from PostGIS, or pre-built for huge datasets, for smooth, styleable maps.
- Real-time
Tile38
In-memory geospatial index with geofencing and live location tracking.
- OGC API
pg_featureserv · pygeoapi
Modern, lightweight OGC API Features and Processes services for developers.
Map front ends
- JavaScript
OpenLayers
The most complete web mapping library: any projection, any OGC service, strong editing and analysis tools.
- WebGL
MapLibre GL JS
Fast, vector-tile based maps with smooth rendering and custom styles. The open successor of Mapbox GL.
- Big data
deck.gl
GPU-powered visualisation of millions of points, lines and 3D features.
- Lightweight
Leaflet
Simple, small and widely known, ideal for straightforward public maps.
Where people work with the data
- Desktop GIS
QGIS
The leading open source desktop GIS: editing straight in PostGIS, cartography, analysis, plugins, and a Python API for automation.
- Field
QField
Mobile data collection on top of QGIS projects, online or offline, with forms and photos.
- Processing
Python · GeoPandas · GRASS · PDAL
Scripted analysis, raster and terrain processing, and point cloud pipelines, run repeatably on servers.
- Surveying
GNU Gama · RTKLIB · PROJ
Network adjustment, GNSS processing and coordinate reference systems for engineering-grade accuracy.
Metadata, portals and spatial data infrastructure
- Catalogue
GeoNetwork · pycsw
Metadata catalogues compliant with ISO 19115 and INSPIRE, for discoverable data.
- Portal
GeoNode · MapStore
Ready-made geospatial portals for sharing data and building map applications.
- Identity
Keycloak
Single sign-on and role-based access across all components, with LDAP and OIDC integration.
What keeps it running
High availability is made of unglamorous, well-understood parts.
- PostgreSQL HA
Patroni · etcd · pgBackRest
Automatic failover, replication and point-in-time recovery for PostGIS.
- Traffic
HAProxy · nginx · keepalived
Load balancing, health checks and virtual IPs for redundant entry points.
- Platform
Docker · Kubernetes · Ansible · Terraform
Containers and infrastructure as code for identical, rebuildable environments.
- Observability
Prometheus · Grafana · Loki
Metrics, dashboards, logs and alerts across every layer.
