| Description | Widespread of user-friendly technology contribute largely to rapid increase of geoinformation users. Their conceptualization of the real world may vary. As the technological interoperability seems to be highly accented and almost solved, elimination of semantic interoperability is still a challenge. Data sharing by different geoinformation communities faces problem of the lack of semantic description which would be understandable across all disciplines. Describing data by using ontologies and ontology sharing may profit both to users and producers of data. Building ontology on geospatial domain and defining bridging concepts for different conceptualization is a crucial task for geographers. Presented paper describes theoretical principles of semantic data integration and annotation. Special attention is paid to domain of emergency management. Semantic heterogeneity issues are demonstrated on practical examples - the case study of topography base definition - on data commonly used in Czech Republic. |
