Abstract

Mobile navigation for inland shipping is an example of a GIS system dedicated to selected group of users. The system concept includes elaboration of dedicated model of mobile cartographic presentation as well as a suitable set of spatial analysis. The basis for both is spatial data derived from publicly available resources. Thus, there is a need of integrating these data. For this particular reason a conceptual data model for the system was created together with suitable importing rules.
The paper presents problems of spatial data integration. The input sources are Inland Electronic Navigational Chart (IENC), topographic data base BDOT10k, database of Vmap level 2 and publicly available data covered by open source project Open Street Map. The final effect to be achieved is multiresolution and multirepresentation database and suitable XML application scheme. Integration problems are caused mostly by inconsistence of geometry and attributes. The first one is mostly influenced by various compilation scales. Additionally, different methods of gathering data used caused that in many places data are not overlaying correctly. Inconsistence of attributes is in fact obvious, when using various data sources, however it is worth mentioning especially in case of OSM. In other sources attribute problems can be easily solved, as they are standardized, but OSM data have their own characteristics and they require manual correction .
The paper gives identification of problems with spatial data integration, but also includes practical approach to selected problems, based on real examples.
