cantons: 26
districts: 144
municipalities: 2,110
edition: 2026-01

One of the examples in the package

A layered SVG coloured from a table with a few lines of plain JavaScript: every entity is a path whose id is its official code. The page shows a part of the country: the two levels share the same borders, so they fit without gaps. The package has every entity of every level.

Ticino: the municipalities of the district of Lugano, coloured by area, among the other districts.

What is in the package

Levels and identifiers

Level	Entities	Identifier
country	1	`CH`
cantons	26	`CH-R-<official code>`
districts	144	`CH-P-<official code>`
municipalities	2,110	`CH-M-<official code>`

Every entity has the same identifier in every file: it is the feature id in GeoJSON and TopoJSON, the id of the path in SVG and the id column of the tables. The history lists 1,294 suppressed municipalities with their successor.

Formats and scales

TopoJSON	5.9 MB	1.2 MB	743 KB	56 KB	428 KB

full: the boundaries as published by the source.
100m: simplified within 100 m and coherent: municipalities, districts and cantons share exactly the same border vertices.
1km: simplified within 1 km and coherent like 100m, every level: the whole country on a web map.
10km: simplified within 10 km and coherent, country, cantons and districts only: small maps and maps of many countries.
At the borders with the neighbouring countries (Austria, France, Germany and Italy) the 100m, 1km and 10km boundaries share the same vertices as in their packages, so the maps fit without gaps or overlaps.
light: country, cantons and districts only, each level simplified on its own to a small file.
GeoJSON: one FeatureCollection per level, WGS84. TopoJSON: all the levels in one topology, shared borders are shared arcs.
GeoPackage: data/geopackage/ch.gpkg (39.2 MB), one file for QGIS and ArcGIS with every level at every scale as a layer (municipalities_100m) with its spatial index, and every table of the package.
Shapefile: one per level and scale, WGS84, UTF-8; the columns longer than ten characters are shortened (region, province, abbrev).
SVG: one file per level and one with every level as a layer, in a Lambert conformal conic projection; they open as layers in Illustrator, Figma and Inkscape.
SQL: a script for PostGIS, one for MySQL 8 and one for SQL Server (3.8 MB each). It creates one table with every entity of every level, its 100m boundary in WGS84 and its indexes.
JSON: data/json/tree.json (176 KB), the levels nested and sorted by name, without boundaries: what the select boxes of a form need.

Tables

CSV, UTF-8. Names in EN, IT, ES, FR, DE, NL, PT, besides the official one.

File	Rows	Content

`tables/municipalities.csv`	2,110	The municipalities: official code, the codes of the parents, names, area, population, elevation in metres (of the centre, or lowest and highest point, as the official source gives it), bounding box, centre and label point. code, name, province_code, province_abbreviation, region_code, cadastral_code, chief_town, area_km2, population, elevation, elevation_min, elevation_max, elevation_mean, min_lat, min_lng, max_lat, max_lng, center_lat, center_lng, label_lat, label_lng, id, name_en, name_it, name_es, name_fr, name_de, name_nl, name_pt
`tables/codes.csv`	2,281	Every entity in other datasets, as Wikidata declares it: the Wikidata item, ISO 3166-2, GeoNames and the OpenStreetMap relation. id, level, code, wikidata, iso_3166_2, geonames, osm_relation
`tables/names.csv`	2,602	Every name an entity is written with (official, each side of a bilingual name, translated), without accents and as a slug: to match a file that has names and no codes. id, level, name, name_ascii, slug, kind
`tables/neighbours.csv`	13,010	The entities of the same level that share a border, both ways, with the length of the shared border in km. level, id, neighbour_id, shared_border_km
`tables/history.csv`	1,294	The suppressed municipalities with the one that replaced them, for archives that still have the old codes; no rows where the official source gives no history. code, name, province_code, replaced_by_code, replaced_by_name
`tables/changes.csv`	0	What changed from one edition of the package to the next, one row per entity added, removed, renamed, moved or with a new boundary: the same as CHANGELOG.md. edition, date, level, id, name, change, before, after
