The region Île-de-France, under the project NumeriSud, supported the action to transforme around 2800 maps that are conserved at the Institut de recherche pour le développement (IRD) library in Bondy into a standard coordinate system. The transformation of the images has been done by Global Mapping Resources (South Africa) under the supervision of R. Zaiss (éditeur) 2014.
