摘要：Implementation of INSPIRE Directive in Poland requires not only legal transposition but also development of a number of technological solutions. The one of such tasks,associated with creation of Spatial Information Infrastructure in Poland,is developing a complex model of georeference database. Significant funding for GBDOT project enables development of the national basic topographical database as a multiresolution database (MRDB). Effective implementation of this type of database requires developing procedures for generalization of geographic information (generalization of digital landscape model – DLM),which, treating TOPO10 component as the only source for creation of TOPO250 component,will allow keeping conceptual and classification consistency between those database elements. To carry out this task,the implementation of the system’s concept (prepared previously for Head Office of Geodesy and Cartography) is required. Such system is going to execute the generalization process using constrained-based modeling and allows to keep topological relationships between the objects as well as between the object classes. Full implementation of the designed generalization system requires running comprehensive tests which would help with its calibration and parameterization of the generalization procedures (related to the character of generalized area). Parameterization of this process will allow determining the criteria of specific objects selection, simplification algorithms as well as the operation order. Tests with the usage of differentiated,related to the character of the area,generalization process parameters become nowadays the priority issue. Parameters are delivered to the system in the form of XML files,which,with the help of dedicated tool,are generated from the spreadsheet files (XLS) filled in by user. Using XLS file makes entering and modifying the parameters easier. Among the other elements defined by the external parametric files there are: criteria of object selection,metric parameters of generalization algorithms (e.g. simplification or aggregation) and the operations’ sequence. Testing on the trial areas of diverse character will allow developming the rules of generalization process’ realization,its parameterization with the proposed tool within the multiresolution reference database. The authors have attempted to develop a generalization process’ parameterization for a number of different trial areas. The generalization of the results will contribute to the development of a holistic system of generalized reference data stored in the national geodetic and cartographic resources.
