    ENSURING THE FUNDAMENTAL SPATIAL DATA QUALITY FOR SUCCESSFUL IMPLEMENTATION OF THE CZECH NSDI

  • Popis výsledku v původním jazyce

    In October 2014, the Czech government approved the conception of The Strategy for the Development of the Infrastructure for Spatial Information in the Czech Republic to 2020 (GeoInfoStrategy), which serves as a basis for the National Spatial Data Infrastructure (NSDI). From the fundamental spatial data point of view, the Register of Territorial Identification, Addresses and Real Estates (RTIARE) can be considered as a cornerstone of the Czech NSDI. The data registered in RTIARE serve as reference data (it means actual, valid and without further verification) for other information systems and decision-making processes in public administration. Therefore, it is crucial to ensure the completeness and accuracy of the data. However, initially RTIARE database was filled by importing data from several data sources that were inconsistent in some cases. By this way some incorrect data got into the register. Administrator of RTIARE, Czech office for Surveying, Mapping and Cadastre (COSMC), solves this problem, it periodically controls and corrects data and its quality improves but without using a geometry part of geographical data. To improve the quality of controls the geometry part has to be used. This paper describes the solution of selected controls, focused on buildings registered in RTIARE based on using both attribute and geometry parts of RTIARE data. A total of four controls were carried out: searching buildings which have identical (near) definition points, searching buildings which have suspicious numbers (house registration), search buildings which have a common bond to the same parcel in cadastre and searching buildings which have a definition point of a building and a definition point of a parcel far more than the maximal distance. Some of the controls were solved by the application of computational geometry algorithms, whereas in some cases the new algorithms had to be proposed.
