The Plan units of the city of Helsinki dataset contains information on the plan units of the current detailed plans.

The plan unit is the smallest unit dedicated for a particular purpose in the detailed plan. It structures the detailed plan on the property level. In the dataset, the purpose of use has been reclassified for reasons of data protection. The classification has been made using the same classification as HSY’s SeutuRamava product.

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