Old Maps Online - A fabulous new online resource

OldMapsOnline has been created by a collaboration between The Great Britain Historical GIS Project based at The University of Portsmouth, UK and Klokan Technologies GmbH, Switzerland. 

Its creation was funded by the Joint Information Service Committee under Strand C: Clustering Digital Content of their Content Programme 2011-13. It is the successor of a project lead by the Moravian Library in the Czech Republic between 2008 and 2011. The portal is based on the MapRank Search technology originally developed for the Kartenportal project in Switzerland.
