This ongoing PhD work focuses on methods to support the mapping of large geospatial conceptual schemas. Specifically, methods that support a domain expert to create mappings and transformation rules that are as free of hidden mismatches, i.e. mappings that map incompatible concepts, as possible. A hypothesis of this work is that this can be achieved by including information on irreconcilable mismatches by making them a formal part of the mapping and by employing visualization and under interaction mechanisms to communicate mismatches to the experts creating the mapping.
