DESCRIPTION:In 2020 National Land Survey of Finland had scanned and digitiz
 ed over 100.000 historical orthophotos from 1931 to 2020. This unique data
 set had been open for a couple of years via a WMS-T API service but was no
 t well known to the public at the time\, and not truly available to less t
 echnically oriented users. Hence\, there was a need to get them findable a
 nd easily accessible with a web browser. \n\nInstead of building a complet
 ely new service\, the images were to be published with the Open Source bas
 ed national geoportal of Finland - Paikkatietoikkuna. The geoportal is bui
 lt with Oskari Map Application Platform which was enhanced for this use ca
 se to support timeseries data. The historical orthophotos are scattered bo
 th in time and in geography. To improve end-user experience and make disco
 vering data easier an OGC API Features service was used for metadata.  \n\
 nThe final result was received with quite a bit of enthusiasm: after publi
 shing the data in Paikkatietoikkuna geoportal in June 2021\, the visitor n
 umbers soared to new records. Nearly all of the feedback has been positive
 \, and now it is possible for anybody to benefit from this extremely valua
 ble and fascinating historical data. \n\nThe code is fully open source and
  can be easily used in any Oskari instance – all you need is the data\, 
 which\, obviously\, isn’t the easiest part of this all.
