Abstract: Metrology system (2) for the management of observation data, this system being configured to collect at least one observation datum and to associate with this observation datum a quality code reflecting the usability of the observation datum with respect to a predefined quality criterion. The system includes a data acquisition module (21); a centralized data management module (22); a data presentation and dissemination module (23); and transverse functional bricks (24) for data processing and production; for end-to-end data quality control; and for intermediation so as to urbanize the architecture and allow the exposure of services.
