The OGE is the delegate of a public service mission to regulate the profession and represents it before the public authorities. The expert surveyor is the only one who can draw up the plans and topographic documents that delineate the land properties. As part of a digital transition process, the OGE wishes to develop an innovative project allowing any citizen to freely access from the GEOFONCIER portal to the graphic part of the cadastral documentation serving the general interest, produced by surveyors-experts and kept by the decentralized services of the Directorate General of Public Finance (DRFiP/DDFiP). The aim of this project to digitise the graphic part of the DMPCs, which is national in scope, is to enable each region to: - Facilitated access to all dematerialised cadastral documentation by ensuring equal treatment of citizens, regardless of the territory (simplification of consultation of documentation: directly online rather than going to a DRFiP/DDFiP); - A digital backup of the cadastral documentation archived in the DRFiP/DDFiP in order to ensure traceability; - A reduction in the tasks of the DRFiP/DDFiP in their mission of archiving and digital updating of cadastral documents; - Modernisation of the management of digitised cadastral documentation; - A positive effect on the environment by limiting travel and impressions.
