Turn scans into maps. Collaboratively.

Georeferencer is an online tool that creates real maps from scanned images.

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 tool that assigns particular geographical location to the image and overlays it over modern maps.


Libraries, archives and other culture heritage institutions have begun a process of massive scanning and publishing of historical maps. Result of this are thousands of scanned images with no reference what the map covers except its original bibliographic record.


Institutions using Georeferencer

Large collections of scanned images have been successfully georeferenced in crowdsourcing pilots of our customers.

Crowdsourcing

Libraries, archives and other culture heritage institutions have begun a process of massive scanning and publishing of historical maps. Result of this are thousands of scanned images with no reference what the map covers except its original bibliographic record.


Georeferencer represents a simple and affordable way to engage online visitors and general public to work on attractive map collections. Via so called “crowdsourcing” the tool can be 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.


3D visualization of maps via Google Earth, overlays with other maps and accuracy analysis of maps are available for each user who wants to conduct research and analysis on the online images as well as just overlay these maps with modern base maps and recent aerial or satellite imagery.

Benefits

Each georeference process enrich existing metadata records with numerical spatial footprint to allow comfortable geographical searching, such as the MapRank Search, in the future. Standardized Web Map Tile Service (OGC WMTS) is delivered immediatelly, so the maps are available directly in a web browser for use in mashups, with no need to install any additional 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 another software.

Requirements

The map collections should provide a table with the list of the identifiers, links and metadata records. The list should be submitted in the form of Microsoft Excel / OpenOffice (XLS or CSV) file and contain unique identifier, image url (direct link to the zoomable image presentation) and image format (jpeg, png, etc..).
