Abstract: Nowadays Geographic information is a mass-product often manipulated by users without expertise in geomatics and who have little or no knowledge about the quality of the data being manipulated. Such context significantly increases the risks of data misuse and of negative consequences resulting from these misuses. This thesis aims at providing expert-users and data-quality experts with a new approach allowing them to better evaluate spatial data quality in order to advise non-expert users. This approach is based on the management of quality information within a multidimensional database and on the dynamic and contextual exploration of quality information through quality indicators displayed into a SOLAP system (Spatial On-Line Analytical Processing) built on a Geographical Information System (GIS).
