“…The Cesium platform, which was created by AGI (Analytical Graphics, Inc., Pennsylvania, United States), is a cross-platform virtual globe for dynamic spatial data visualization. It is an open-source JavaScript library for building a world-class 3D Earth platform and for providing the best performance for visualization [17][18][19]. Second, according to the GeoSOT global split technology, the earth space is decomposed into a multiscale nested space stereo grid system that assigns a unique split code to each stereo.…”

Currently, the rapid development of cities and the rapid increase in urban populations have led to a sharp increase in urban components, making precise urban component management, query efficiency, and operational visualization urgent problems to be solved. In this paper, an in-depth study is carried out, pointing out that the current two-dimensional map or component management method based on a real-life three-dimensional city has defects, including query difficulty, fuzzy management, and inefficiency, and it is impossible to accurately and efficiently manage urban components. Then, this paper uses a combination of GIS technology and BIM technology as the starting point. On one hand, this combined technology is based on the high efficiency of the underlying data organization of the GeoSOT grid code and the accuracy of real geographic location expression; on the other hand, based on the integrity of the building information representation and the accuracy of the relative position of internal components of BIM, a precise urban component management method based on GeoSOT grid code and BIM is proposed. Finally, based on this method, a real-time 3D Earth visualization platform is established by using the Cesium platform. Taking the fire hydrant component management of the commercial Guanlan Street in Baiyin City, Gansu Province, China as an example, the precise management of the components in this area is realized, which proves that the method can achieve precise urban component management.

“…Multi-surface coordinates were converted to an array and then provided to the Cesium Primitive API for visualization. An example of the JavaScript code that provides coordinates of a building unit to Primitive API is as follows: There are several studies [29][30][31][32][33][34] that use Cesium library as a platform for visualization of 3D cadastral data, smart city applications, BIMs (Building Information Modeling) and other spatial data. Figure 4 provides an example of multi-surface geometry visualized by Cesium JavaScript library.…”

3D cadastral systems are more complex than traditional cadastral systems and they require more complex technical solutions and innovative use of developing technologies. Regarding data integrity and data consistency, 3D cadastral data should be maintained by a Database Management System (DBMS). Furthermore, there are still challenges regarding visualization of 3D cadastral data. A prototype of the 3D cadastral system based on a NoSQL database and a JavaScript application for 3D visualization is designed and tested in order to investigate the possibilities of using new technical solutions. It is assumed that this approach, with further development, could be a good basis for the development of a modern 3D cadastral system. MongoDB database is used for storing data and Cesium JavaScript library is used for 3D visualization. The system uses an LADM (Land Administration Domain Model) based data model. Additionally, script languages, libraries, application programming interfaces (APIs), software and data formats are used for the system development. The case study is based on the real cadastral data. The underground object and building units located below and above the ground level are used to test the proposed data model and the system’s functionality. The proposed system needs further development in order to provide full support to a modern 3D cadastral system. However, it allows maintenance of 3D cadastral data and basic 3D visualization with the interactive approach.

“…In previous works, virtual scenes such as Unity, X3DOM, and Three.js have been used extensively to develop tools dedicated to the public [13,15,20,22]. Additionally, virtual globes such as Nasa World Wind, Cesium.js, and Skyline were often proved to be very effective in a participatory context [19,[23][24][25][26][27][28][29]. In fact, virtual globes succeed in citizen participation by offering features available in Google Earth and with which the public is familiar (e.g., zoom, panoramic overview, visualization of planning projects, activation of feature inspection).…”

Web-mapping has been widely used to facilitate citizen participation in smart cities. Web-mapping has evolved from 2D static maps towards more dynamic and immersive 3D worlds such as virtual globes and scenes. Although current technologies allow us to build multidimensional representations, there is still a lack of research studies on how to further leverage them to foster citizen participation. Information on space–time changes can be an important asset for a successful citizen participation process. Citizens may need to track the evolution of their city over space and time, and how their participation will impact the urban planning and decision-making process. Consequently, the main objective of this research study is to design and develop a multidimensional (2D, 3D, 4D) web-mapping platform where citizens can better assess and understand the spatiotemporal evolution of their cities. User testing was conducted to assess the multidimensional representation of the animations used, and the spatiotemporal mechanism and interface features. Results showed that it is recommended to integrate spatiotemporal simulations to citizen participation platforms so citizens can better assess the impacts of their choices. We also assessed that 3D does not always communicate information better than 2D. Future work will aim at testing the platform in a consultation process with a representative sample of participants.
