Download services for geodata are usually made available via standard web services (e.g. the Web Feature Service by the Open Geospatial Consortium (OGC)) and Application Programming Interfaces (e.g. the OGC API - Features).
Web interface: data.geo.admin.ch / opendata.swiss
The data.geoadmin.ch website is a «list based» interface providingenccess to packaged geospatial data.
REST Interface: Spatial Temporal Asset Catalog API
The data.geo.admin.ch Spatial Temporal Asset Catalog – API is a «dataset based» download service providing access to packaged geospatial data and related metadata.
