The article describes the 5-steps harmonization framework – a complex attitude to the harmonization of spatial planning data as the importance of this process is still rapidly increasing. The reason is building of spatial data infrastructures and sharing of data coming from various resources in an unified structure. The principles shown in the article are generally valid, in this particular case the 5-steps harmonization framework was tested upon the spatial planning data. The motivation for the research was primarily the European Directive Infrastructure for Spatial Information in the European Community (INSPIRE) that states that each European Union member state must provide selected data according to the INSPIRE technical implementing rules. The innovative feature of the presented 5-steps harmonization framework is using of ontology that is used for managing of heterogeneity of spatial data from various data themes. As different institutions, organizations or companies are involved e.g. in spatial planning and building of spatial data infrastructures more technical options for data harmonization realization have been explored. The first way how to practically realize the 5-steps harmonization framework was using the ontologies and Extract-Transform-Load (ETL) tools. Further research aimed at exploring of capabilities of traditional relational database management systems and their spatial extensions for harmonization. Third, the focus was also put on traditional vendors of geographic information systems (GIS) and using of world widespread GIS for realization of the 5-steps harmonization framework. Finally the article summarizes the pros and cons of various approaches that have been explored.
