VivaMap uses only official open-data sources — primarily Swiss federal sources, complemented by OpenStreetMap for points of interest. No proprietary databases, no commercial licences. This page lists every source actually used in production with its licence, update cadence, and direct link to the official portal.
Why open data only?
Two reasons. (1) Durability: access conditions on a commercial database can change overnight. Federal open geodata are guaranteed by the Geoinformation Act (GeoIG). (2) Trust: everything is traceable, everything is citable, with no confidentiality clauses.
Federal sources
Most environmental, demographic, and tax data come from federal offices. The default licence for federal geoinformation is Open by default (attribution required, no share-alike obligation).

Third-party sources
For point-of-interest density — health, education, dining, culture, leisure — VivaMap relies on OpenStreetMap, the global community mapping project.
OSM— OpenStreetMap
| Source | Feeds | Licence | Cadence | |
|---|
| POI: health (doctors, clinics, hospitals, pharmacies) | Health | ODbL (attribution + share-alike) | Quarterly (Geofabrik extract) | Official portal ↗ |
| POI: education (schools, libraries, museums, playgrounds) | Education & culture | ODbL | Quarterly | Official portal ↗ |
| POI: dining and nightlife (restaurants, bars, cafés) | Nightlife & dining | ODbL | Quarterly | Official portal ↗ |
| POI: retail and local services | Commerce (planned) | ODbL | Quarterly | Official portal ↗ |
Recompute cadence
Scores are recomputed on every major source update: yearly for most (Arealstatistik on a ~12-year cycle but GWR quarterly; noise, public-transport, taxation yearly), quarterly for OpenStreetMap. No real-time refresh: VivaMap reflects long-term average use, not the instantaneous state of a neighborhood.
