Land Administration Data Dissemination Processes: A Case Study in Croatia

In the first edition of LADM the land administration processes were omitted as they were considered to be country specific. This view is now under reconsideration as the future extensions of LADM are planned and developed. The processes within land administration domain are, namely, registration and dissemination. The research concerning modeling of the LAS processes is somewhat in a scarce state as the majority of the research was directed towards registration activities such as subdivision, real-property transfers, and property formation. The authors deem that the proper dissemination of LAS data is a prerequisite to above-mentioned processes, and it could be stated that this domain of the land administration dynamism is relatively poorly researched. The research presented in this paper analyzes one use-case scenario of land administration data dissemination process in Croatia. The analyzed use-case depicts the process in which cadastral certificates are utilized to gain additional land-related information, which in this case study, was the spatial planning data concerning one cadastral parcel. The aim of this research was to examine how the land administration data dissemination processes could be optimized and improved in a standardized formal manner. The model outlining the process of disseminating both cadastral and spatial planning certificates was formalized by means of usecase diagram. From the formalized process, the elements, such as actors, activities, input/output data were determined and matched with existing LADM classes, while the importance of data interoperability and timeframe of the said processes were also addressed. The paper also discussed how would the formalized process look if the LAS data was interoperable within one service, pointing out that this would lead to a much more timeefficient and user-friendly access to the disseminated LAS data for the current and future LAS users.
