District division of Helsinki

Description

The Helsinki district division data includes the boundary lines of the districts within the city, as well as the names and identifiers of the areas. The district division system of Helsinki is a regional division of the entire area of Helsinki created for administrative purposes. The district divisions consist of the following area levels: major district, district, city sub-district and small district. The initial data for the maintenance of the district divisions is the base map and up-to-date detailed plans. The data is maintained in vector form in the Oracle Spatial database. District divisions are constantly updated on the basis of decisions made by the city geodesist. The data is maintained by the City Survey Services of the City of Helsinki Urban Environment Division. The district division data is published as open data as the boundaries change. **Previewing the data in the map.hel.fi service:** - [Major districts](https://kartta.hel.fi/link/dBxyPD) - [Districts](https://kartta.hel.fi/link/dBy5wU) - [Small districts](https://kartta.hel.fi/link/dByF8N) - [All base maps layers active](https://kartta.hel.fi/link/dBwxnX) - All base map layers can be found on the website: [https://kartta.hel.fi/](https://kartta.hel.fi/?setlanguage=en) > Layers > Background Maps > Base maps **Coordinate systems:** - Maintained in ETRS-GK25 (EPSG:3879), can be projected to other coordinate systems.

For the years 1995-2000, the data is missing the boundaries of small districts. The source of the publication is the Seutu-CD produced by HSY and the Regional Map published on it. This [Excel file](https://www.hel.fi/hel2/tietokeskus/data/helsinki/Helsingin_aluejaot_2016.xlsx) contains the Helsinki regional divisions for 2016 covering all area levels. The file contains the area codes of the Regional Map, the official regional names of Helsinki and the code+name used by Statistics Finland in its data. The second data consists of postal area codes for city sub-districts and small districts on their own tabs. In particular, the city sub-districts do not fit inside postal areas precisely in all areas (see the [map](https://www.hel.fi/hel2/tietokeskus/data/helsinki/Postialue_Osaalue.jpg)).
