Welcome to the main official GitHub organization of the French National Institute for Geographic and Forest Information (IGN).

IGN develops, maintains, and provides authoritative geographic, environmental, and forest information to support public policy, scientific research, economic development, and citizen services.

IGN is committed to fostering an open and collaborative software ecosystem by sharing and maintaining open source projects that contribute to the geospatial commons.

Our objectives are to:

• Promote transparency and reuse of public sector software.
• Improve software quality, security, and sustainability.
• Foster collaboration with public administrations, academia, industry, and the open source community.
• Contribute to open standards and interoperable geospatial infrastructures.
• Support innovation in geospatial technologies and digital public goods.

Our open source projects support the entire geospatial data value chain, from data production to end-user applications.

Tools and components supporting the collection, processing and qualification of geographic information.

Examples include projects related to imagery, LiDAR, geospatial processing, data transformation, and AI-assisted geospatial workflows.

Solutions for cataloguing, hosting, managing and publishing geospatial datasets and services.

Key projects:

• cartes.gouv.fr – The main access portal to the French Geoplatform, including catalog, data store and publication services.
• Geoplatform publication and hosting services.
• Metadata, access control and geospatial service management tools.

Components that provide interoperable and standards-based access to geospatial resources.

Tools helping data producers, GIS analysts and administrators manage their data and services.

Key projects:

• Géoplateforme QGIS Plugin – Publish, manage and consume Geoplatform services directly from QGIS.
• QGIS ecosystem extensions and collaborative plugins.

Applications and libraries enabling the creation, visualization and sharing of maps.

Key projects:

• Ma Carte – Open source online mapping and storymap tools developed by IGN.
• Map viewers and visualisation components.
• Cartographic editing and publishing applications.

We actively contribute to:

• Open standards and interoperability.
• Open source geospatial communities.
• European digital commons.
• Public-sector digital platforms.
• Responsible and transparent use of AI for geospatial applications.

Contributions are welcome.
