This repo hosts Swiss canton and municipality geodata in open formats that can be used to build static and interactive maps (e.g. with D3).
The following formats are available:
The ESRI Shapefiles are generated with QGIS using the 'V200' municipality area Shapefiles (QGIS wouldn't combine the cantons with the 'swissBOUNDARIES3D' files). Foreign municipalities are removed.
The CRS is set to WGS84 because that's the default for GeoJSON.
The simplified shapefiles are generated with MapShaper, using the Visvalingam algorithm with 50% simplification.
Run rake geojson to generate the GeoJSON files from the shapefiles. Useful feature properties are automatically populated and converted to camelCase. Coordinates are rounded to a precision of 3 with LilJSON.
Run rake topojson to generate the TopoJSON files from the GeoJSON files. Note that the simplified files are using the non-simplified GeoJSON as input and are simplified using TopoJSON with the -s 10e-9 setting.
