Summary, in English

Geoportals are increasingly used for searching, viewing, and downloading spatial data. This study concerns methods to improve the visual presentation in viewing services. When spatial data in a viewing service are taken from more than one source there are often syntactic, semantic, topological, and geometrical conflicts that prevent maps being fully consistent. In this study we extend a standard view service with methods to solve these conflicts. The methods are based on: (1) semantic labels of data in basic services, (2) a rule-base in the portal layer, and (3) integration methods in the portal layer. To evaluate the methodology, we use a case study for adding historical borders on top of a base-map. The results show that the borders are overlaid on top of the map without conflicts, and that a consistent map is generated automatically as an output. The methodology can be generalized to add other types of data on top of a base-map.
