Quarters of Helsinki

The Helsinki Blocks dataset is made up of [planning units] maintained by City Measurement Services (https://hri.fi/data/fi/dataset/helsingin-planning units) with the status "Valid" and the characteristics of the municipal register. Blocks are formed by combining geometries with the same block identifier. The planning unit is the smallest unit reserved for a specific purpose in the local detailed plan. The use of the data has been reclassified for data protection reasons. The material can also be downloaded in several different formats, including: JSON, KML, GIF, Tiff, GeoTiff, JPEG, PNG, CSV, Esri Shape. The available formats can always be found with the [GetCapabilities](https://kartta.hel.fi/ws/geoserver/avoindata/wfs?request=GetCapabilities) survey.
