The 4th action of the Geomatics Operational Plan for Wallonia aims to define the content of the Walloon Georeferential and to ensure the availability of the first reference geodata of guaranteed quality, in line with the business needs of users. The project "Geodata Quality Assessment Process: application to the Walloon Georeferential" proposes to analyse the workflow of the existing quality analysis process in order to bring it into line with current standards, consolidate it and improve it where necessary. In close consultation with the Technical Committee (TC-georef) of the Walloon Public Service and the Department of Geometrology, this project aims not only to improve the quality control workflow but also to propose adaptations to the acquisition process for geodata that do not meet international rules and standards.
