The search engine for historical maps

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 thanks to funding from JISC. Since January 2013 is the project improved and maintained by volunteers and the team of Klokan Technologies GmbH in their free time.

The website has been created by Klokan Technologies GmbH, specialists in online map publishing and in applications of open-source software. It aims to demonstrate a combination of tools for publishing historical maps with a focus on their easy accessibility for the general public. The core of the retrieval system is the MapRank Search software, developed originally for the Swiss Kartenportal.CH project. The web is optimised for search engines with GeoSEO powered by Linked Data, and it also exposes Structured Data ( microdata). The technology and expertise from this project can be applied on another projects on request.
