Helsingfors orthofoto

Description

This dataset provides the orthophotographs of Helsinki in GIS API from 1932 to present day. Additionally, photos from 1988, 1976, 1969, 1964, 1950, 1943 and 1932 are provided as image files. The Helsinki area is photographed from the air at regular intervals. Exact dates for each year's photographs can be seen [here (document in Finnish)](http://www.hel.fi/hel2/tietokeskus/data/dokumentit/Helsingin_ortoilmakuvat_kuvausaikat.pdf) An orthophotograph is an aerial photograph or satellite imagery geometrically corrected ("orthorectified") such that the scale is uniform: the photo or image follows a given map projection. The limitations by the Territorial Surveillance Act have been considered before publishing the data and the guidelines issued by the Finnish Defence Forces have been followed. **Previewing the data in the map.hel.fi service:** - [Orthophotograph 2023](https://kartta.hel.fi/link/dEcYPr) - [False colour orthophoto 2023](https://kartta.hel.fi/link/dEdVpN) - All aerial phograph layers can be found on the website: [https://kartta.hel.fi/](https://kartta.hel.fi/?setlanguage=en) > Layers > Background Maps > Aerial Photographs / False Colour Aerial Photographs **Coordinate systems:** - WMS/WMTS API: Maintained in ETRS-GK25 (EPSG:3879), can be projected to other coordinate systems.
