Abstract
Uncertainty management is necessary for spatial data and GIS applications. This paper focuses on topological relationships and uncertainty in spatial data regions. We discuss the representation of vague regions using the RCC-8 theory and show how rough sets can improve on this methodology through the use of its indiscernibility relation and approximation regions
