LADM Based Utility Network Cadastre in Serbia

Abstract

The utility network cadastre in Serbia is the main register of utility lines and the rights to them. The Law on State Survey and Cadastre states the necessity for implementing a unified information system of both a real estate and utility network cadastre, but this has not been achieved in practice. The reasons for such a unified information system are to ensure easier maintenance of the rights of both the utilities and properties located above or below them, to ensure more efficient procedures for obtaining the consent for placement, repair, or removal of the utility line, to prevent procedures being executed based on outdated data, to build an information system as the law prescribes, and to facilitate the business processes in the Serbian geodetic authority, since it is responsible for both registers. Therefore, an already-developed LADM (Land Administration Domain Model)-based country profile for Serbia should be extended to include information from the utility network cadastre. An analysis of Serbian legislation showed the necessity of extending the class set of the utility network cadastre by further specialization of the LADM LA_LegalSpaceUtilityNetwork class. Furthermore, such a system will support the maintenance of utility network data. In practice, when there is a change made on utility lines by the right holders, it is necessary to implement the change in the register. In many situations, this is not done, and the actual state does not correspond to the one in the register. Usually, modern technologies, such as ground penetrating radar (GPR) and LIDAR, are used for data acquisition in order to provide an update of the utility network data. Since these technologies produce 3D data, we analyzed how to link that data to the traditional 2D spatial paradigm.

Modelling underground cadastral survey data in CityGML

“…LADM is a leading international 3D data model in the land administration domain. In recent years, several studies have worked on developing LADM-based country profiles for underground areas (Dželalija & Roić, 2022;Janečka & Bobíková, 2018;Kim & Heo, 2017;Radulović et al, 2019;Ramlakhan et al, 2023;Saeidian et al, 2022;Silva & Carneiro, 2020;Yan et al, 2019Yan et al, , 2021. However, these studies mostly focused on the legal spaces attached to underground assets.…”

Smart Contract Application for Managing Land Administration System Transactions

“…International Organization for Standardization defines ISO/CD 19152:2021 Geographic information -Land Administration Domain Model (LADM) as a reference domain model for basic information-related components of land administration and provides basics for country profiles. According to [20], this standard has been applied for the creation of various country profiles all over the world [21]- [24] and has grown over the years in recognition and influence.…”

Applications of GIScience for Land Administration

“…The geographical frame provided by the land administration data can also be used to manage network data. Radulović et al [26] show, how data on utility networks can be modelled based on the LADM. Since the utility lines are either above or below the ground, some aspects of 3D cadastres are relevant here as well.…”
