Libraries, archives and other culture heritage institutions have begun a process of massive scanning and publishing of historical maps. A scanned map is only a picture and not a map at all: it is not searchable geographically and cannot be compared with other maps. Georeferencer is an online service that turns the existing scans into true maps and can be easily integrated in institution’s website.
Georeferencer gives libraries and archives an affordable and simple way how to engage online visitors an general public to work on attractive map collections, provides 3D visualization of maps via Google Earth, creates overlays with other maps, delivers standardized Web Map Service (OGC WMS) and in the same moment also enrich existing metadata records with numerical spatial footprint to allow comfortable geographical searching, such as the MapRank Search, in the future.
The tool can be via so called “crowdsourcing” used by staff as well as by volunteers, either in groups explicitly organized for this task by the institution or simply recruited from online visitors and general public. In all cases, everybody can through an easy and enjoyable process georeference the scanned historical maps and then visualize them in 3D, conduct research and analysis on the online images as well as overlay these maps with modern base maps and recent aerial or satellite imagery.
All features are available directly in a web browser, without a need of installing any software neither in the institution nor on the side of the online visitors.
The participating libraries receives the produced metadata, which can be easily embedded into existing library catalog in a form of MARC field 034 or Dublin Core DCMI Box by the library. It is also possible to export GeoTiff or GIS-ready geodata for processing the maps in anther software.
