Map service

The City of Helsinki map service is a map portal that can be used to access the map and geographic information datasets of several departments. The portal can be used to locate buildings and other real estate, city plan maps and register information about locations. 

The portal gives access to many basic maps, for example, the guide map, the various versions of the real estate map, orthophotographs, and a large collection of historical maps and aerial photos. 

You can utilise the map service on the City of Helsinki map service website
