The application of the Land Administration Domain Model in building a country profile for the Polish cadastre

Land administration in different countries is carried out through various institutions or agencies. There are two institutions in Poland that perform these activities. They are cadastre and land registry. Cadastre scope concerns mostly spatial information, whereas land registry does generally the legal one. The Polish cadastral model is defined within sixteen diagrams and applying Unified Modelling Language (UML) notation. It results in fact, that it is possible to be understood by only small number of professionals. The construction of Polish cadastral profile based on ISO 19152 “Geographic Information - Land Administration Domain Model (LADM)” application was described in the paper. The resulting profile presents the main relationships within the Polish cadastral system. Since the profile is simpler in perception than the original cadastral model, it can be used by the wider public, and is therefore more beneficial for improving land administration in Poland. It can also help to reduce data redundancy and may facilitate cadastral data transfer and exchange between different countries.
