canton open data

Cantons of the France, 2025. Electoral cantons (post-2015 redécoupage). code_insee is the canton code. Dropped: numero_du_canton, composition_du_canton, codes_insee_des_arrondissements (list-valued). REPUBLISH 2026-07-20: first publication shipped 2054 — dropEmptyFeatures discarded 2 cantons as GeometryCollections (RFC7946 winding artifacts, decision 0020); driver fix coerces to MultiPolygon, restoring 2056.

Cantons (Kantone) of the Switzerland, 2026. ADM1. 26 cantons. kantonsnummer is the BFS canton number. REPUBLISH 2026-08-26: replaces cm_ffO3WrU5wcmx (dataset 0t0FFDIeuKrA), whose geometry was transposed (lon/lat swapped) by the boundary axis-swap defect: a 3D interchange GeoJSON is stamped EPSG:4979, whose authority axis order is (lat,lon,h), and ST_Transform honoured it. Fixed by always_xy=true in geo-ingest/crs.ts. These are the exact bytes verified on dev as 9zM39IwAWVmm — promoted, not re-produced, so prod and dev carry byte-identical geometry. Gate: bounds bracket the source exactly, 26/26 features.
