ViennaGIS is the Geographical Information System (GIS) of the City of Vienna . It provides a comprehensive and sustainable spatial data and spatial services infrastructure for the Viennese city administration, the economy, but also for all citizens interested in geoinformation. ViennaGIS comprises a large data pool of geographic data (ViennaGIS geodata management), an infrastructure to be able to access this data via electronic communication services, applications for processing, visualization and analysis of geospatial data as well as interfaces and license models for their reference.

History of origin

The foundation stone for the development of geographic data processing was laid in the Vienna city administration as early as the 1970s. One of the triggers for the new tasks was the increasing need for regional analyzes. In the beginning, digitization was still carried out manually, but due to new developments in the device sector, data could soon be recorded with original accuracy and saved electronically.

As the first major project, a generalized reference system was digitized - the so-called spatial reference system Vienna (RBW). In the 1970s, people began to create computer city maps on the basis of aerial photographs. In order to reduce the positional errors, the street space was completely re-measured. This large - scale multi-purpose city map (MZK) project was carried out together with the municipal surveying department MA 41. The result was a topographical map base with a high quality covering the whole area. Since the advent of Internet technology and the availability of the first Internet browser in 1995, ViennaGIS has made numerous geodata freely available on the Internet via interfaces and applications.

ViennaGIS spatial data budget

With the ViennaGIS spatial data budget, the City of Vienna now has a comprehensive spatial data pool that is managed centrally by the City of Vienna's ICT service provider and updated decentrally by the departments responsible for the respective spatial data. In the context of Open Government Data, almost all geodata from the ViennaGIS geospatial database can be obtained and processed free of charge, provided that it is not subject to property rights.

ViennaGIS on the Internet

All ViennaGIS internet services are summarized on the ViennaGIS homepage. By far the most successful GIS application is the city map, which is used up to 100,000 times a day. Above all, the specialist applications such as environmental assets, cultural assets or the zoning and development plan offer access to current geographic data from the Vienna city administration. The ViennaGIS infrastructure ensures that the data of the ViennaGIS spatial data repository can be used efficiently internally by the City of Vienna and made accessible externally on the Internet via interfaces and applications.

ViennaGIS is, together with the other countries of Austria, a partner in the geodata network geoland.at of the Austrian countries.

With basemap.at, the federal states created one of the most widely used open government data products between 2012 and 2014.

Together with Lower Austria and Burgenland , the State of Vienna operates a traffic data network. Among other things, this is the basis for the intermodal traffic router AnachB.at.
