GDH has done a number of projects in the Il de France Region. One of the most prominent are the digital models done in collaboration with Dr. Pierre-Yves Gagnier of the Muséum National d’Histoire Naturelle in Paris. Here GDH scanned both galleries and specimens in two museum campaigns.

Another important project was scanning the interior, exterior, caves, and features of the Château de La Roche-Guyon, a Medieval Castle, Historic palace, important tourist location, and home of the Duc de La Rochefoucauld. Dr. Laurant Costa of the CNRS in Nanterre, and Mr Bertrand Triboulot of the Direction régionale des affaires culturelles d’Ile-de-France, Service régional de l’archéologie, collaborated on this project.
