OldMapsOnline developed out of a love of history and heritage of old maps. The project began as a collaboration between Klokan Technologies GmbH, Switzerland and The Great Britain Historical GIS Project based at the University of Portsmouth, UK […] Since January 2013 is the project improved and maintained by volunteers and the team of Klokan Technologies GmbH in their free time. […] OldMapsOnline.org indexes over 400.000 maps. This is only thanks to the archives and libraries that were open to the idea and provided their online content. All new participants are warmly welcomed.
