Abstract
Abstract. Urbanization phenomenon is a key role that contributes to the smart cities development. The expansion of urban growth requires everything to be smart and controlled by advance technology for efficient urban management. One of the important aspects that often overlooked in realizing smart cities is asset management. Asset management is an approach for managing, monitoring and maintenance of assets. Previous studies showed that there are several efforts in managing asset by integrating the asset with Geographic Information System (GIS). However, several limitations can be seen from the studies such as unavailability of real visualization and limitation on asset descriptions although we believe that 3D offers rich information and real visualization for asset management practice. Therefore, to achieve an effective asset management, we proposed to conceptualize the asset with the latest version of CityGML 3.0. The aim of this paper is to model the immovable asset using CityGML 3.0 concept. We adopted the concept of occupied and unoccupied spaces to model the public hall, owned by Johor Bahru City Council (MBJB). The hall was modelled based on point cloud data set from Terrestrial Laser Scanning (TLS) and Unmanned Aerial Vehicle (UAV). The attribute data for the hall was stored in 3DCityDB for information retrieval and query. The result showed that the hall was successfully visualized and information regarding the asset can be retrieved. With this approach, it is believed that an effective 3D asset management system can be developed in the future, to ensure adequate system performance and effective cost operational.
Highlights
Smart cities have received a lot of attention in various fields
According to Bahri et al (2019), efficient asset management can be achieved with the integration of Geographic Information System (GIS) due to the advancement of GIS in handling spatial and attribute data
In Malaysia, the Immovable Asset Management Procedures (TPATA) provided by the federal government is to guide all government agencies in managing various assets and properties owned by government (0.0 et al, 2020)
Summary
Smart cities have received a lot of attention in various fields. According to Bismart (2020), the main concept of smart city is to employ advance technology in delivering services and solving problems in the city. A smart city employs information and communication technology (ICT) to boost operational efficiency, to share data with the public, and to improve government service and citizen welfare (TWI, 2021). In 3D asset management, the data model is utilized to facilitate information sharing, and to discover the spatial and semantic information and the thematic features in 3D city models. The integration of geometry and semantics in a single data model paved the way for better sharing of virtual 3D city models with the inclusion of thematic modules in OCG CityGML (Saran et al, 2018). In this study we proposed to conceptualize the asset with the latest version of CityGML 3.0
