Examination of Compatibility Between the Croatian Land Administration System and LADM

Croatian land administration system faces a great crossroad because it demands for a single maintenance solution of digital cadastral plans converted from an analogue to a digital form a few years back. Joint Information System of Land Books and Cadastre is currently under development. For the cadastral system transformation compliance with international standards is very important. Furthermore, introduction of the new geodetic datum and the new cartographic projections adopted in 2004 is still in its implementation phase. At the same time, Croatia is in the process of being admitted into full European Union membership (expected accession date is July 1, 2013). This chapter examines compatibility of the Croatian land administration system with the Land Administration Domain Model (LADM). Possibility of LADM adoption in the Republic of Croatia is evident from comparison of LADM literature and the current situation of the Croatian land administration system. This chapter proposes a national LADM profile for the Republic of Croatia. Interconnections between classes of the Croatian land administration system and linkage possibilities of these classes with LADM are presented through relevant examples.

Overview of the Croatian Land Administration System and the Possibilities for Its Upgrade to 3D by Existing Data

This paper explores the laws and other legal acts related to the Croatian 3D cadastre with an emphasis on those which relate to interests in strata, spatial planning, and other regulations that are valid or were valid on Croatian territory. The effects of the application of these regulations on the present situation of registration in cadastre and land register were considered. This paper also explores current legal, institutional, and technical solutions implemented in the Croatian Land Administration System and the possibilities for its upgrade to 3D cadastre. Implementation of any technological option to establish a 3D cadastre is tightly related to legislation. Hence, legislation and technological options are considered to find solutions that will be possible to implement. One suggestion presented in this paper was to use other sources of 3D data such as topographic signs or symbols used to represent topographic objects on 2D maps. In combination with other geodetic and cartographic products, useful information can be obtained, often quite relevant to provide a reference context for a 3D cadastre. Topographic signs on topographic maps and on other geodetic products provide a representation of complex real-world situations (tunnels, bridges, overpasses etc.) that are not usually presented on cadastral maps. This paper presents the possibility of utilizing those topographic signs to achieve the first steps towards establishing a 3D cadastre. Furthermore, this study proposes the establishment of a 3D Multipurpose Land Administration System as the most efficient system of land administration in a time when spatial information is easier to obtain than ever before and traditional real estate registers are subject to frequent and demanding changes.
