The DigDag project, short for Digital atlas of the Danish historical-administrative geography, is a research project funded by The National Programme for Research Infrastructure under the Danish Agency for Science, Technology and Innovation.

Ranging from 2009 to 2012, the aim of the project is the etablishment of a database structure which can tie the Danish administrative districts together geographically and historically. This will provide a historical-administrative GIS platform for the digital humanities allowing to:

• establish a historical-administrative research infrastructure of Denmark c. 1600–
• form the backbone of future historical and administrative research
• create a powerful search engine for use in the service functions of archives, collections and libraries

As source data will be used Det digitale matrikelkort, the digital cadastre, and the basic unit will be the ejerlav, the townland.

Participants in the project are a range of major Danish research institutions with a focus on historical and administrative research together with the major Danish heritage institutions and archives. See the Participants page.
