|b Activities in mapping sciences are experiencing vast improvements on almost a daily basis. Today, spatial information is playing important roles in decision-making. In this respect, GIS is a strongly recognized technique, which hosts all traditional mapping information, and improves spatial information effects through strong heterogeneous databases. \ Accordingly, traditional quality control processes, used to assess spatial mapping data, cannot handle all quality aspects of spatial information hosted in a Geographical Information System (GIS). This means that the traditional standards for positional accuracy, lineage, logical consistency \ and completeness constitute only partial measures for assessing GIS contents in a fully integrated spatial system. \ This paper presents a quantitative mathematical model and strategy to facilitate the quality control (Q.C.) process of a GIS. The model (called the DEMAIS Model) treats geometric and descriptive data of a GIS in precise and global modes. \ The model has been developed based on least-squares theories and concepts. It was tested and found to be successful. In a research to be published soon, automation facilities that are under development for the model will be presented.
