Gateway to the Hungarian aerial photo archive of FÖMI
The Institute of Geodesy, Cartography and Remote Sensing (FÖMI) successfully finished the Digital Aerial Photograph Archive project, founded by EU, on 30th June 2014.There are almost a half million frames in the archives from the period of 1959 - 2005. By the end of the project we have finished digitizing the frame centres of all photos and the scanning of 15 % of the aerial photo archive of FÖMI. The digitized aerial images can be freely browsed on the Internet at fentrol.hu. After an open registration every user can tag, comment or annotate a photo. The original scanned images can be bought online (including georeference files also), or could be downloaded in reduced resolution for free-of-charge.
In the presentation we will show the steps of creating the digital aerial photo archive (fentrol.hu) highlighting the most popular usage fields of the available data. We also introduce how crowdsourcing can help improving the georeference information of the aerial photos, plus we give some international examples of such online databases.
