Introduction
The Canadian Historical Documentation & Imaging Group, known as CANADIGM, was founded in 2011 to digitally record the historic sites, documents and artefacts related to Canadian history – especially those the general public might otherwise not have the chance to experience.
 
CANADIGM is a not-for-profit group based in London, Ontario consisting of visual artists, photographers, former educators, mechanical technicians, as well as media and logistics professionals. The tie that binds us together is a dedication to preserve Canadian history.
The group’s current project is called Souterraine Impressions. It involves documenting, researching and recreating images and carvings made in 1917 by Canadian soldiers hiding from the enemy in underground caves in France prior to the Battle for Vimy Ridge. These First World War soldiers carved into the chalk walls to pass the time, but also to leave behind something by which to be remembered – something which has never before been documented. Some of the men were hidden underground for weeks awaiting orders to join the historic battle. This was the first time all four divisions of the Canadian Expeditionary Forces worked together for a common purpose and the Battle for Vimy Ridge was not only a great military success but became for Canada a symbol of national unity, achievement and tremendous sacrifice.
CANADIGM has documented the soldiers’ carvings, an has researched the men who did them. We are bringing them out of the darkness and into the light of the public domain. We are the only Canadian organization to thoroughly document the Canadian soldiers who were in those caves.

How we work
CANADIGM digitally records sites, documents and artefacts by creating, in a non-invasive manner, digital files using the latest photographic and documentation techniques. These files are archival quality and available for educational and historical research purposes through our archival data bank. By using 3D laser scanners, the finest details can be captured without touching the surface or disturbing an artefact’s natural patina. The 3D image can then be reproduced using a 3D printer, for example, or through a variety of modern machining processes. These images can also be turned into 3D digital files suitable for use on the Web. The high-resolution photographs produce digital image files between 300 and 600 megabytes, which provide extraordinary detail. 
CANADIGM’s services are also available to public institutions and educational facilities that do not have the resources to document artifacts and objects themselves, but would like to have them in a digital format. For further information, please contact us at ~info@canadigm.ca~. We’d be happy to discuss your project.
