Regional geographic information
We produce and compile regional geographic information to support expert work. In addition, we also share geographic information materials and register data as open data.
We provide both open geographic information materials and those subject to licence from the Helsinki region. The materials cover the most important register data, map materials and other geographic information to support planning. The numerous and easy-to-implement geographic information materials serve planners and researchers in the Helsinki metropolitan area in their daily work.
- In addition to the geographic information materials subject to licence, we have materials that are open to all. You can find them on HSY’s open data pages. In addition, all open data in geographic information format is also available via an interface as well as from the HSY open data map service.
- The register data we produce is based on the information in the regional basic register, or SePe. SePe is a database that combines basic register data from different sources into a single dataset covering the entire Helsinki metropolitan area. In addition to the register data for Espoo, Helsinki, Kauniainen and Vantaa, SePe includes building-level population data (DVV) as well as company and business location data (Statistics Finland). You can utilise SePe’s data, for example, in SeutuRuutu or via an interface.
