Safe construction heights and maximum estimated significant wave height in Helsinki

Data produced by the Finnish Meteorological Institute on the safe construction height and the largest estimated significant wave height in the Helsinki area. The material can also be downloaded in several formats, e.g.: JSON, KML, GIF, Tiff, GeoTiff, JPEG, PNG, CSV, Esri Shape. The available formats can always be found in the [GetCapabilities] (https://kartta.hel.fi/ws/geoserver/avoindata/wfs?request=GetCapabilities) questionnaire. **Coordinating system(s):** — ETRS-GK25 (EPSG:3879). Maintenance coordinate system. The data can also be projected to other coordinate systems. Other possible coordinates can be found in the GetCapabilities document of the interface service. **Addresses of interface services:** — WFS interface: [https://kartta.hel.fi/ws/geoserver/avoindata/wfs](−) **WFS levels** — FMI_High_estimated_marking_wave height_point — FMI_Safe_building heights_point Administrator: City of Helsinki, Urban Environment Industry, Services and Permits, Urban Surveying Services **Level FMI_High_estimated_marking_wave height_point characteristics** — information service_id (int).
