ÉVALUATION DE LA QUALITÉ DES GÉODONNÉES ET OPERATIONALISATION DE LA DIRECTIVE INSPIRE : RETOUR D'EXPERIENCE

In the same way as the French Référentiel à Grande Echelle (RGE), the Walloon Public Service aims to set up its own Georepository. This repository is intended to respond to the establishment of an Infrastructure for Spatial Information in the European Community under the INSPIRE directive. It consists among other things in ensuring the availability of the first reference geoadata whose quality is guaranteed and in coherence with the business needs of the users for the Walloon territory. With this in mind, the Geomatics Unit of the University of Liège, in collaboration with the Technical Committee of the Public Service of Wallonia for the Georepository and the Geometrology Departement, proposes a quality control methodology for three prospective geodata of the Georepository: buildings, road axes and addresses. One of the outcomes of this project was the definition of a theorical basis for the validation of geodata quality. This article presents its main findings and conclusions.
