GeoJSON boundaries for French administrative divisions including regions, departments, arrondissements, cantons, and communes.
France Geojson is a comprehensive collection of GeoJSON files containing the boundaries of French administrative divisions. It provides accurate geographic data for regions, departments, arrondissements, cantons, and communes, solving the problem of accessing clean, optimized French administrative boundaries for mapping and data visualization projects.
Developers and data scientists building mapping applications, data visualizations, or geographic analysis tools focused on France, particularly those needing administrative boundary data.
Developers choose France Geojson because it provides ready-to-use, optimized GeoJSON files with proper metadata and organization, eliminating the need to process raw IGN shapefiles themselves while maintaining geographic accuracy and performance.

Includes all levels from regions to communes with INSEE codes and names, providing ready-to-use hierarchical data for integration.
Uses Visvalingam weighted simplification and coordinate precision reduction to 5 decimals, balancing accuracy with web-friendly file sizes.
Offers data in national files and subdivided by region/department, allowing selective loading based on geographic scope.
Provides pre-2015 metropolitan region boundaries, useful for historical comparisons without additional processing.
Missing data for arrondissements in Mayotte and Martinique, and omits several overseas collectivities, limiting comprehensive territory mapping.
Based on 2018 data from INSEE and IGN, so it may not reflect recent administrative changes, requiring manual updates for current applications.
The 25% simplification reduces file size but sacrifices geometric accuracy, making it unsuitable for high-detail mapping or analysis needs.
