• 2D Land cadastre on the present territory of the Republic of Croatia has been continuously developed in the last 200 years. Throughout the years, survey methods, needs and purposes of cadastre have changed. This resulted in a variety of cadastral data with different accuracy and completeness. Today, we can collect an enormous amount of data and the need for cadastral data has never been greater. We need to find feasible solutions to make the initial acquisition of 3D cadastral data which would satisfy the needs of stakeholders involved in Land Administration System (LAS). This paper will present a historical background of the cadastral data acquisition which would help to understand circumstances on how this variety of available cadastral data has been produced and the data available nowadays. Based on the historical overview and the overview of the current state, we will upgrade the data model of a LAS used in Croatia to support the implementation of a 3D cadastre. The model will include its static components but also proposed improvements of cadastral resurvey related processes. The Land Administration Domain Model (LADM), which in 2012 became the ISO 19,152 standard, will be used as the formal basis. This paper offers a proposal for cadastral resurvey improvements, better registration of public rights and registration of separate parts of real properties. It will identify and explore critical points and make recommendations to bring Real Property Cadastre closer to a real 3D register.
