Land Administration Domain Model (LADM) covers basic information related to components of land administration (including elements above and below the earth surface and including water areas). It includes agreements on data about administrative and spatial units, land rights in a broad sense and source documents. The rights may include real and personal rights, informal rights as well as indigenous, customary rights. All types of restrictions and responsibilities can be represented. Overlapping claims to land may be included. Cadastral and land books data play important role in many fields directly or indirectly associated with their use (land surveying, civil engineering, architecture and urban planning, agronomy, transport, forestry, tourism, etc.). So far, similarities and differences between the existing Croatian land administration system and LADM have been investigated. Objective of this paper is to determine compatibility between Land Administration Domain Model and Croatian Land Administration System. Compatibility is determined with following questions: – What are users’ requirements for the Croatian land administration system? – Which LADM classes can be applied directly to the Croatian land administration system? – Which LADM classes have to be modified to be suitable for the Croatian land administration system? – How to design a land information system for the Croatian land administration system complying with LADM? This paper gives answers to the previous questions. LADM country profile Croatia has been developed and key requirements, concepts, and functionalities of Croatian Land Administration System (LAS) have been identified. Conceptual Croatian LAS model comprising the LADM framework have been elaborated. This paper proposes two new classes for the model (HR_OldCadastralSurvey and HR_LegalityOfTheBuilding). Some types in the code lists have been changed and added to suit to the Croatian LAS.
