Abstract

Digital twins (DTs) have been found useful in manufacturing, construction, and maintenance. Adapting DTs to serve cities, the question arises of what an urban digital twin should contain and how it should be orchestrated to serve a city’s dynamical ecosystem, along with how to enhance the efficiency of the city. We are aligning with the commonplace idea that the main advantage of using DTs is economical as, for example, DTs can improve the planning of activities thus saving money and time. But how can they be useful for a city? Instead of looking at the DTs as solutions in search of problems to be solved, we start from city needs. Our approach is two-fold. We start by briefly reviewing existing possibilities for meeting some specific needs, but keep the focus on identifying and attempting to close the gap between the needs arising from everyday city functions and the latest DT techniques useful for meeting those needs. DTs are technically different and serve different applications, yet they share a common identity and name, as well as several technical similarities. Adopting computer science terminology, we see a back-end city DT as the container of all information, while any single front-end, visualized or used either by humans or robots, offers a limited but meaningful representation of the DT for a specific application. Alas, there are multiple open questions regarding the realization and benefits of such back-end DT. Nevertheless, we discuss how the back-end DT (or any specific DT) could be updated autonomously from sensor data using artificial intelligence techniques, and how the front-ends could be used for large benefits to the entire city ecosystem.

Abstract

he paper focuses on approaches to the registration of real property rights in the case of underground or subwaytunnels in different EU countries: Austria, Bulgaria, Czech Republic, Croatia, Greece, Poland, Slovenia, andSweden. The authors conducted analysis on the registration of rights to subway tunnels in the chosen countries,including its effectiveness in ensuring appropriate property rights to construct and exploit tunnels. Special at-tention was given to limitations related to the lack of legal provisions vertically dividing space, i.e. into layers,and referring to the ownership right to the layers. Benefits which might be achieved by the introduction of a 3Dreal property subdivision were pointed out. The analysis of the available data concerning the geometry ofsubway tunnels in particular countries was presented. The authors tried to answer the question whether theaccessible data concerning the geometry of subway tunnels allows to generate a 3D geospatial model of aconstructed object, and to specify the space which should be determined as a 3D parcel in the 3D real propertycadastre, for the purpose of registering property rights for the object (the tunne The paper focuses on approaches to the registration of real property rights in the case of underground or subway tunnels in different EU countries: Austria, Bulgaria, Czech Republic, Croatia, Greece, Poland, Slovenia, and Sweden.
