Helsinki stock map

Helsinki’s base map is a large scale (1:500) map maintained by City Measurement Services in the urban environment industry, which is used as a basis for planning and planning urban development. The base map serves as a base map for the city plan and is also used for the production of many special maps. The base map is the most accurate spatial dataset describing the City of Helsinki. It is kept up-to-date at a scale of 1:500. The Kantakarta describes the terrain sites that are important for construction and design and some boundaries. The data includes, for example, real estate, buildings, traffic routes, naming and tags, waterways, elevation data, land and plant cover, hull points, district division and other sites. The data has been produced through aerial photography, terrain measurements and real estate deliveries as well as building permit processing measures. The base map corresponds to the quality requirements of the base map maintained by the municipalities (formerly the Agency Map). The imaging technique of the base map is defined in [Publication No 94 of the National Institute of Land Surveying (2003)](http://docplayer.fi/718645-Maanmittauslaitos-maarays-1-1-keskushallinto.html). The base map is used to produce statutory ground maps for town planning. ** Coordinate system(s):** — ETRS-GK25 (EPSG:3879). Maintenance coordinates. The data can also be projected in other coordinate systems. Other possible coordinate systems can be found in the GetCapabilities document of the interface service. **Height system(s):** — N2000. **Addresses of interface services:** — WMS interface: [https://kartta.hel.fi/ws/geoserver/avoindata/wms](https://kartta.hel.fi/ws/geoserver/avoindata/wms?request=getCapabilities) — WMTS interface: [https://kartta.hel.fi/ws/geoserver/avoindata/gwc/service/wmts](https://kartta.hel.fi/ws/geoserver/avoindata/gwc/service/wmts?request=getCapabilities) **Published levels:** — Stock map (including WMTS) — Kantamap_grey — Kantamap_white — Kantamap_Limits — Kantakartan_terrain information (including WMTS) — Kantamap_bottom — Kantamap_pallets — Map series — Map series_grey
