Street Names of the City of Helsinki

The dataset includes the official place names of Helsinki, i.e. the names of streets, parks and other public areas confirmed in the detailed plans. The names are in Finnish and Swedish. The names are accompanied by the naming criteria and other possible additional information, such as the previous name and changes in spelling. In addition, the data includes the names of the areas according to the administrative division of the city (city districts, city sub-districts, districts).

The dataset also contains the names of public places maintained by the City of Helsinki that have been processed by the place name committee, such as sports parks and marinas, even if they have not been confirmed in the town plan. Place names are maintained as part of the Municipal register of Helsinki (Facta system).

Place names are designed and validated as part of the detailed plan process. The place name committee, which consists of experts in the history of Helsinki, the Finnish and Swedish languages, urban planning and urban culture, prepares the name proposals.

The dataset is updated in connection with the planning process and the work of the place name committee.

The data is available for download in several formats, including JSON, KML, CSV, Esri Shape, and XML. Available formats can always be found under OutputFormat in the GetCapabilities query for the service.
