Kartenportal.CH is the specialist portal for maps from Switzerland’s libraries and archives and was originally operated by Elektronische Bibliothek Schweiz (e-lib.ch). The portal is now a cooperative project between the following institutions:
Zentralbibliothek Zürich (general management)
ETH Zürich, ETH Library
Federal Office of Topography swisstopo
Kantonsbibliothek Vadiana St. Gallen
Lib4RI: Library of Eawag, Empa, WSL & PSI, Dübendorf
Swiss National Library
The map search uses data from the Swiss metacatalogue swissbib, the catalogue of libraries of universities and federal institutions. The data is synchronised with swissbib on a daily basis, re-indexed and made accessible via a search interface that has been optimised for maps. The map search is based on the software MapRank Search developed by the company Klokan Technologies GmbH, Unterägeri.
