What Oslandia does

Oslandia is a French open source GIS architecture firm specializing in consulting, custom development, training, and support services built around the QGIS and PostGIS ecosystems. Founded circa 2009-2011 and headquartered in Paris with a second office in Lyon, the company serves French government agencies, large enterprises in energy, transportation, and telecommunications, and research/NGO organizations. Its customer base includes EDF, TotalEnergies, SNCF Reseau, Egis Rail, Mappy, La Poste, Orange, CNRS, INSEE, CNES, SHOM, INRAP, and Conseil Departemental de la Haute-Garonne, among others.

Oslandia's technology portfolio centers on core committer contributions to QGIS and maintenance of several open source libraries and plugins, including SFCGAL (a C++/CGAL wrapper for ISO 19107 3D geometry operations), Giro3D (a JavaScript/WebGL 3D visualization library built on Three.js), py3dtiles (a 3D Tiles converter), pgPointcloud (a PostgreSQL point cloud extension), the QGIS Versioning plugin, and CityForge (a QGIS plugin for generating CityJSON 3D building models from point clouds). The firm contributes 3D feature development to QGIS releases (notably QGIS 4.0 Norrkoping) and provides QGIS Server deployments, QWC/QWC2 web client configuration, QField Cloud rollouts, and PostGIS-based data pipelines.

Oslandia's business model is services-led, monetized through custom consulting engagements, professional training programs, and ticket-based support and maintenance contracts. Pricing is quote-based with no public rates disclosed. The company operates a dual go-to-market combining direct enterprise sales with a community-led approach anchored in OSGeo membership, OGC French Forum participation, Systematic Paris-Region/GTLL and Imaginove cluster involvement, Open Invention Network membership (since February 2025), and sponsorship of FOSS4G, GeoDataDays, QGIS User Days, and LiDAR events. Recurring revenue from support contracts is layered atop project-based consulting, and the firm maintains an active technical blog, GitHub repositories with workshop materials, and a Mastodon/LinkedIn presence to drive thought leadership and lead generation.
