Toward a Croatian utility registration implementation model based on LADM

This paper reviews approaches to utility registration and analyzes the Croatian utility cadaster and utility registration regulations. In Croatia, utility networks are registered in the national utility cadaster administered by State Geodetic Administration, with private companies obliged to send reports on all changes to the utility networks that they manage. The Croatian utility cadaster, besides data about managers and geometry of utility networks, registers various technical data about physical utilities. This paper then analyzes the land administration domain model (LADM) and LandInfra standards and their abilities to model both legal and physical features of utility networks that need to be registered in the Croatian utility cadaster. As some jurisdictions look on utility networks as separate legal objects that can be owned or leased, possibilities to model all attributes needed in the Croatian utility cadaster with an LADM-based model was further investigated. Finally, the paper proposes a utility registration implementation model based on LADM that can describe both physical and legal features of utility networks
