According to the advances in Information & Communication Technology (ICT), nowadays, the use of Internet of Things (IoT) has become a normal part of daily life. It allows interconnections among a wide variety of devices and sensors such as smartphones, smartwatches, automobiles, or any object with a built-in sensor. However, these devices and senso...

The latest coronavirus (namely severe acute respiratory syndrome coronavirus 2 or COVID-19) was first detected in Wuhan, China, and spread throughout the world since December 2019. To tackle this pandemic, we need a tool to trace and predict trends of COVID-19 at global, national, and regional levels rapidly. Several organizations around the world...

The recent advancement in Information & Communication Technology (ICT) is seen as a critical enabler to design intelligent smart cities targeting different domains. One such domain is modes of transport in a city. Currently, various cities around the world are envisioning innovative ways to reduce emissions in the cities by increasing physically ac...

In this paper various schemes for visualizing geo-spatial data such as Computational Fluid Dynamics (CFD) data are explored. The architecture of a new Smart Cities Platform is presented and examples of the visualization capabilities are given. Results show that scalar and vectorial measurands, such as wind pressure and wind directions, may be prese...

Devices from the Internet of Things are being increasingly used in everyday life, and they provide a massive amount of data in various formats. While implementing the Smart Cities initiative, these data are integrated and utilized together with the 3D city model for further applications. Based on Open Geospatial Consortium standards, heterogeneous...

We evaluated the suitability of encoding a CityGML 3.0 indoor model for one of the Stuttgart University of Applied Sciences (HFT Stuttgart) campus buildings, using I3S Building Scene Layer (BSL). I3S BSL is a new enhancement provided in the OGC I3S version 1.3 community standard enabling the representation of building elements, such as roofs, walls...

Simulation modeling has been playing a significant role in predicting energy transition scenarios. With the rising demand for real-time solutions, simulation tools are making their way through different stages of energy planning, i.e., from design to the commencement phase. So, the main objective of this research is to compare the workflow and outp...

There is increased activity in developing workflows and implementations in the context of urban energy analysis simulation based on 3D city models in smart cities. At the University of Applied Sciences Stuttgart (HFT Stuttgart), an urban energy simulation platform called ‘SimStadt’ has successfully been developed. It uses the CityGML 3D city model...

Urban digital twins have become an essential factor for cities and communities to visualize, simulate and analyze data. The conventional geospatial standards work great with online platforms such as CesiumJS or ArcGIS API for JavaScript. However, their usage in different platforms such as game engines has not been well established yet. Game engines...

As the world has more urbanized, cities need to assess and manage their building energy performances in order to achieve energy-reduction goals. The urban digital twins (UDT) offer promising solutions to this demand by providing valuable insights with qualitative and quantitative information about the building environment. The urban building energy...

Nowadays, the digital 3D city models are the basis of the urban data platform. It plays an essential role in various fields of industry and research, from urban resource planning, environmental simulation, disaster management, and many more. Especially, there is more and more use of 3D city models in 3D visualization applications. However, one comm...

Solar photovoltaic (PV) is a key technology for any renewable energy system. As subsidy-free PV becomes more and more economically feasible, region-specific planning tools that define areas suitable for ground-mounted PV are needed. While many top-down studies have assessed suitable areas at a national scale, an accurate scalable bottom-up assessme...

The OGC Interoperable Simulation and Gaming Year 2 Sprint advanced the use of relevant OGC and Khronos Group standards in the modeling, simulation, and training communities through capability development, compatibility testing, and gap analysis. Of particular interest was the use of glTF models, game engines, and 3rd-party mobile device libraries f...

This paper explains the development of a 3D city model-based Public Participation Platform as a prototype and its implementation in a real-world public participation process to redevelop the Weilimdorf area of Stuttgart city. Alongside conducting Weilimdorf’s public participation process, the goal of the mentioned public participation platform is t...

Urban platforms are becoming a vital role player in city resources management for achieving the right balance between social and economic services and their impact on the environment. More and more cities are starting to benefit from an urban platform to state the city conditions and re-coin the shape of life depending on data gathered from differe...

The goal of the OGC ISG Sprint was to advance the use of relevant OGC and Khronos standards in the modeling and simulation community through practical exercise and testing of the draft specification produced by the 3D Data Container and Tiles API Pilot (and the associated YouTube Playlist). Of particular interest was the handling and integration of...

The concept and implementation of Smart Cities is an important approach to improve decision making as well as quality of life of the growing urban population. An essential part of this is the presentation of data from different sources within a digital city model. Wind flow at building scale has a strong impact on many health and energy issues in a...

This Engineering Report summarizes the purpose and key results of the 3D Data Container and Tiles API Pilot, an OGC Innovation Program initiative conducted between October 2019 and July 2020. In the context of both existing and emerging 3D and 2D standards, the focus of the Pilot was on the exchange and visualization of 3D data using open standards...

As the world continues in the quest to fight global warming and environmental pollution by gradually moving to renewable sources of energy, there is also a need to reduce building energy consumption by refurbishing old and historic buildings to meet the required energy standards. While this approach may differ from city to city across the globe, th...

In this paper, we present a concept for an urban energy dashboard built using different Open Geospatial Consortium (OGC) standards integrated with 3D city models. With cities continuously pressed to cut upon their carbon emissions, it becomes vital to visualize different energy data under one application. This perfectly fits ourvision of developing...

Decreasing the number of accidents with cyclists is seen as a major challenge in German politics, accordingly being integrated into the coalition treaty of the German federal government. However, targeting measures to increase the ob-as well as safety should be considered when formulating measures to increase cycling these two safety aspects. To in...
