Switzerland's open data, made accessible

The Swiss Federal Government strongly supports open data principles — creating a foundation for informed decision-making that benefits both policymakers and the public, while unlocking the potential of data-driven innovation. ^[1]

Geoda.ch is built on Swiss open data related to real estate. We collect and combine information from public registers and archives. While these datasets are often published in complex GIS formats intended for specialists, Geoda.ch transforms them into clear, accessible insights for every address in Switzerland. Just as oil powered the industrial era, data is the key raw material of the digital age — Geoda.ch acts as a refinery, turning raw information into practical knowledge. ^[2]
