The Geographic Information - Land Administration Domain Model was formally published by International Organization for Standardization on the 1st of December 2012. At the same time, although independently, the new model of Polish cadastral system has been being prepared. It is defined as the part of the new order concerning the ground and building cadastre, that has stage of final draft now. The author’s idea is to prepare initial Polish cadastral profile, based on LADM. The application schema of cadastral database was built applying UML notation, according to the ISO 19100 series standards methodology. The Polish cadastral model contains 71 classes, that are presented at 16 diagrams and grouped in 8 thematic packages. The first step was to chose the main classes of Polish cadastral model, provide them with English names and assign related LADM classes. The results are presented in tabular form in the paper. The next step was analysis of diagrams presenting the Polish cadastral model and identifying the key connections among its classes. Subsequently, the key connections between classes concerning “Objects”, “Parties” and “Rights to Properties” of Polish cadastral model were identified and presented graphically using Unified Modelling Language. Classes from packages “Address” and “Lease” were partly or fully omitted as considered not important for building LADM country profile for Poland. Then the two diagrams – one concerning “Objects” and the other with “Parties” and “Rights to Properties” were merged into one diagram. As the result seemed too complicated, some similar associations were substituted by one connection with some constraints. Some connections which seemed necessary at this stage were also added. The obtained result, together with diagram describing relationships between classes PL_Change, PL_LegalDocument, PL_TechnicalDocumentation and PL_GeneralObject are suggested to present profile of Polish cadastral system. Since the order defining the Polish cadastral model is not published yet, some small corrections in the proposed form of Polish country profile may be introduced if necessary.
