The Swiss Federal Geoportal (geo.admin.ch) is a federal government platform that facilitates public access to Swiss spatial data. It contains more than 500 geodata sets originating from a variety of federal bodies, as well as more than 20 thematic portals. geo.admin.ch was created in response to the Federal Geoinformation Act, and is designed to more effectively disseminate comprehensive geoinformation for both professionals and the general public. Anyone who wants can view, print, and order geodata. The site is visited by an average of around 50,000 users per day.
geo.admin.ch is an open architecture operated by the Federal Office of Topography (swisstopo):
Open Source: The software stack of the Swiss federal spatial data infrastructure is based almost entirely on open source software, from operating system to application level. The source code is all on GitHub.
Open Standards: The use of open standards grants access to data and data services and ensures dissemination of geodata.
Open Access: Data access was made easier on the one hand through the open data services geo.admin.ch offers and on the other hand by providing an open application programming interface.
Cloud Computing: Using public cloud services (IaaS) avoids the time-consuming purchase of hardware. Automatic provisioning enables the public body to scale its number of servers by a factor of ten in less than an hour.
geo.admin.ch contributes functionality back to the core ol3-Cesium code base where this would be useful for other applications. Follow them on Twitter.
