This research evaluates the effectiveness of orthogonal, multi-view, and spherical projection techniques in the semantic segmentation of LIDAR-captured point clouds. Using U-Net, a deep learning architecture originally designed for biomedical image segmentation, the study processed 2D projections of point clouds to generate segmented images. Post-segmentation, label spreading was employed to map these labels back to the 3D point cloud. The orthogonal projection emerged as the most proficient, achieving an overall accuracy of 92% and a mean IoU of 49.69%. Multi-view projection, capturing occluded surfaces, registered slightly lower metrics, while spherical projection lagged with 82% accuracy due to inherent data warping. The findings underscore the pivotal role of projection techniques and U-Net in point cloud segmentation, suggesting orthogonal projection as the optimal approach for the most applications.

The paper presents a new hierarchy of multiple levels of detail (LoD) designed for the modeling of underground utility networks. The hierarchy of LoDs is applied to water management possible scenarios in the context of determining the aging of distribution networks. The hierarchy of LoDs proposes four levels, two sublevels, and three quality levels. The various LoDs are defined based on the dimension of the space and the geometric primitives, the topology, the semantic aspects, the contextual information, and the data quality (regarding 3D data collecting). It is believed that this number of levels is sufficient and appropriate to cover the modeling of underground utility networks suitable for various applications and consequently will help increase the use of 3D UUN models and their sharing.

Nowadays, our society is in the transit to adopt more sustainable energy sources to reduce our impact on the environment;one alternative is solar energy. However, this is highly affected by the surroundings, which might cause shadowing effects. In this paper, we present our method to perform shadowing calculations in urban areas using semantic 3D city models, which is split into five sections: Point Grid Generation, Sun-Ray Generation, Nightside Filtering, Bounding Volume Hierarchy and the intersection between the sun rays and the BVH to identify which locations are shadowed at a given moment (epoch). Our tests are performed in Rotterdam's city center, a dense urban area in The Netherlands. Our initial results indicate that the computational time per 100 k grid points fluctuates within 0.2-0.7s.

This paper discusses two experimental Augmented Reality (AR) projects conducted by collaboration between the University of North Carolina at Charlotte and the Levine Museum of the New South in the City of Charlotte, USA between 2018 and 2021. These projects employ 2D mapping, 3D procedural modeling, and marker-based mobile AR techniques for data visualization focused on social and economic issues in Charlotte on a neighborhood scale. AR offers an interactive method to expand visualization capabilities in GIS. These projects show that mobile AR applications can support local community events that are aimed at expanding overall public participation with a goal of increasing awareness of neighborhood changes over time through 3D data visualization. Surveys from the demonstration events show that a majority of event participants learned new information about the demographic and economic changes over the past two decades in their communities through the AR experiences with 3D data mapping.

Semantic 3D city models have been widely used to solve problems that affect the human-built environment. Due to the complexity of the city and its dynamic aspect, these models should allow studying the evolution of a phenomena in real time. Therefore, 3D city models are evolving towards Digital Twin of cities to allow handling the dynamic aspect of the city. For instance, such evolution requires real-time data to be collected using Internet of Things devices (IoT). This kind of dynamic data requires specific tools that should allow its particular exploitation and manipulation. To model the urban environment, CityGML and CityJSON for instance, as international 3D standards, allow creating, storing and exchanging 3D city models in an interoperable way. This paper aims to propose and implement a methodology for integrating real-time data in a city model by using the "Dynamizer" extension of CityGML based on CityJSON. We then have developed a web interface plugin to handle IoT data and their interactive visualization as a first step for future simulations. This solution allows the understanding of the 3Dcity model encoded with JSON, also the simplification and the easy comprehension of the Dynamizer extension compared to the CityGML solution which is difficult to decipher. The solution also makes it possible to establish the connection between the physical entities and their digital twins, to followthe evolution of their real characteristics over time, to represent them, analyze them and take the appropriate decision to preserve the components of the territory, to manage it correctly and ensure its resilience and sustainability.

This paper investigates the interactions between sidewalk delivery robots and pedestrians in urban settings to evaluate pedestrian safety and robot efficiency in shared spaces. We developed a 3D digital twin environment model that allows realistic simulation of robot-human and robot-cityscape interactions, adopting the Pedestrian Aware Model (PAM) to ensure effective and safe navigation. Using an agent-based modeling approach, we analyze various scenarios involving pedestrians, wheelchair users, and robots sharing sidewalk spaces. Our findings reveal that robots do not inherently contribute to sidewalk congestion and can be programmed to maintain a buffer zone that allows for both safety and efficiency, suggesting their potential for smooth coexistence with pedestrians. We observed that robots caused most collisions, while pedestrians were primarily responsible for proximity violations of minimum distance thresholds, emphasizing the need for further research and strategies to reduce further the risks associated with these incidents. The results suggest that with careful design-oriented planning and continued research, robots can safely and comfortably share sidewalks with pedestrians, contributing to a more harmonious and efficient urban landscape. Our proposed simulation model can assist urban planners, policymakers, and researchers in evaluating the influence of various design interventions and policies on human-robot coexistence in cities, marking a crucial step toward accommodating both humans and robots in urban spaces.

Solid waste (SW) management is a crucial challenge for urban sustainability. With global waste generation exceeding two billion metric tons every year, it poses various negative impacts, including health risks and environmental contamination. Despite not being a primary SDG, addressing SW management is essential for achieving several goals, as it relates to 12 out of 17 SDGs. South Africa, in particular, struggles with issues as large generation, and inadequate waste collection services. To address these challenges, a dynamic model incorporating real-time monitoring, optimized collection routes, and citizen participation is proposed. This study case involves a real-time citizen engagement method to locate, identify, and visualize SW containers and littering sites via open-source tool called Epicollect5 based on geospatial information. This can be considered as a first step towards a Digital Twin for SW management. In a three-day data collection campaign, a total of 1270 containers and 820 littering sites were identified. The result show inadequate distribution of containers in public spaces, highlighting the need for citizen involvement in reporting container information to achieve a comprehensive understanding of their distribution. Additionally, the concentration of litter reports in peripheral park areas emphasizes the importance of providing well-distributed containers and prompt maintenance. The inclusion of photographs in reports helps identify areas requiring immediate attention, while citizen participation mitigates challenges associated with location accuracy and resource requirements. Digital twinning, multi-stakeholder engagement, and citizen participation provide insights into waste container distribution and combating illegal dumping. This approach benefits lower-income countries with limited resources, improving SW management practices.

3D spatial data are widely used to simulate various urbanistic phenomena, thanks to their valuable semantic, geometric, and topologic information. CityGML is a highly adopted data standard for semantic 3D city models, providing a standardized description of the cityscape that enables interoperability across different stakeholders. When future scenarios for urban development are simulated, the simulation results can be visualized and further analyzed in synthetically generated 3D city models. However, land use and constructability regulations are often overlooked when generating synthetic 3D city models for simulation purposes, despite some regulatory urban constraints having a direct impact on simulation results. For instance, the roof shape is highly correlated with building solar energy potential, while the zoning maximum allowed number of apartments directly influences the buildings' urban density estimation. Therefore, integrating such constructability knowledge within 3D city models is crucial. This paper proposes a framework for mapping urban planning rules defined in the German XPlanung standard onto 3D city models structured in compliance with CityGML to ensure legislative validity and real-life applicability. We review related work, discuss the structure of CityGML and the main elements concerned by urbanistic laws, explain the main concepts of XPlanung, and investigate the mapping of regulatory information with CityGML entities.

Point clouds and high-resolution 3D data have become increasingly important in various fields, including surveying, construction, and virtual reality. However, simply having this data is not enough;to extract useful information, semantic labeling is crucial. In this context, we propose a method to transfer annotations from a labeled to an unlabeled point cloud using an octree structure. The structure also analyses changes between the point clouds. Our experiments confirm that our method effectively transfers annotations while addressing changes. The primary contribution of this project is the development of the method for automatic label transfer between two different point clouds that represent the same real-world object. The proposed method can be of great importance for data-driven deep learning algorithms as it can also allow circumventing stochastic transfer learning by deterministic label transfer between datasets depicting the same objects.

Densely populated premodern human settlements relied on a diverse range of ingenious agricultural techniques. Although most of these techniques have been abandoned and forgotten, chinampas in Mexico City have somehow prevailed. Chinampas are a unique premodern technique that is based on creating artificial islets for agricultural activities. Although debatable, premodern agricultural practices such as these have recently gained interest because of the insights they might hold for future food production practices. Some consider that these last active remnants of premodern society could be considered sustainable because of the manner they have managed to combine cultural and environmental conservation with continuous agricultural productivity despite rampart urbanization. Better understanding and continuous monitoring of regions such as these are important not only for cultural and environmental preservation but as potential blueprints for future food systems design. Assuming maintaining vegetation and moisture levels as well as controlling urban sprawl are key elements for chinampa conservation, this paper suggests using open access Sentinel 2A images and R to create multi-temporal spectral index raster stacks can be used to assess changes between years, seasons in months in the communal lands known as Ejidos of Xochimilco and San Gregorio Atlapulco. If so, low cost monitoring methods such as these can be used in local governments that have limited funds for specialized software, hardware and human resources.
