Welcome to Georeferencer

Georeferencer is a collaborative research and education platform which allows annotation and personalization of historical map collections available on the web. It is able to 
turn scanned images into true maps. 

This online tool allows visual integration of historical map layers and overlaying these on top of aerial imagery and modern base maps. It is also possible to find maps processed by Georeferencer and covering a particular area of interest within different online map collections at http://www.oldmapsonline.org/.

The early beta of the Georeferencer service is available online at: http://www.georeferencer.org/

A new version of is under active development. See the roadmap for more info.
