INTEROPERABILITY CADASTRAL DATA IN THE SYSTEM APPROACH

Abstract

Elements of each system and their interrelationships can be represented using models simulating reality. Analysis of the problem with the use of modeling methods facilitates the identification of the problem, its diagnosis and assessment of data quality. In this study, the method of semantic modeling, based on the principles of system analysis was used. The thematic scope of the publication covers the use of these methods in order to develop a model of cadastral data in Poland. Real estate cadastre is one of the most important information systems in the world, based on the spatial data of geodetic and legal nature. It is therefore important to define appropriately its purpose, scope of data and the links between objects, subjects and their assigned rights. The methods of system analysis are widely used for this purpose around the world. By using of these methods the schematic diagram of the multi-purpose cadastre in Poland was developed, along with the model of sources and types of cadastral information. Particular attention was paid to modeling of the scope and content of spatial data. The basic assumption of the functionality of the cadastral system is the interoperability of data, from selected databases collecting information about cadastral objects with the use of thematic groups if the INSPIRE Directive. Spatial conditions of data interoperability of modeled multi-purpose cadastre based on current law conditions in Poland were presented in this paper.
