Urban Social Space and Sustainable Development
Urban social space and sustainable urban development are both prominent areas of research in urban studies. The development of a city is closely tied to the development of its social space. The level of sustainable development in a city can be assessed by examining the evolution of its urban social space. Therefore, the two are highly interconnected in a close relationship. However, the social dimension of sustainable development has always received the least attention compared to the economy and the environment.

Urban Scene Reconstruction via Neural Radiance Fields
3D reconstruction of urban scenes is an important research topic in remote sensing. Neural Radiance Fields (NeRFs) offer an efficient solution for both structure recovery and novel view synthesis. The realistic 3D urban models generated by NeRFs have potential future applications in simulation for autonomous driving, as well as in Augmented and Virtual Reality (AR/VR) experiences.

Urban Road Traffic Spatiotemporal State Estimation
The road traffic state is usually analyzed from a temporal and macroscopic perspective; however, traffic flow parameters, such as density and spacing, can explain the evolution of traffic states from the microscopic perspective and the spatial distribution of vehicles in lanes.

Urban Resilience Assessment
This paper aims to provide a better understanding of the state of knowledge on urban resilience assessment through mapping the knowledge domain and highlighting emerging trends during different periods. The objects of study were 420 papers published in the Web of Science from 1998 to 2020. Science mapping was done using VOSviewer and CiteSpace, two widely known software tools for bibliometrics analysis and scientometric visualization. The results show that research published on urban resilience assessment was very limited and fragmented until 2009, and the focus has mainly been on risk mitigation and vulnerability assessment. The intellectual base grew between 2010 and 2014, when a paradigm shift from approaches based on robustness and reliability toward more adaptation-oriented approaches occurred. Finally, the annual publication trends have grown rapidly over the past five years and there has been more emphasis on climate change adaptation and flood resilience.

Urban Remote Sensing with Spatial Big Data
During the past decades, multiple remote sensing data sources, including nighttime light images, high spatial resolution multispectral satellite images, unmanned drone images, and hyperspectral images, among many others, have provided fresh opportunities to examine the dynamics of urban landscapes. In the meantime, the rapid development of telecommunications and mobile technology, alongside the emergence of online search engines and social media platforms with geotagging technology, has fundamentally changed how human activities and the urban landscape are recorded and depicted. The combination of these two types of data sources results in explosive and mind-blowing discoveries in contemporary urban studies, especially for the purposes of sustainable urban planning and development. Urban scholars are now equipped with abundant data to examine many theoretical arguments that often result from limited and indirect observations and less-than-ideal controlled experiments. For the first time, urban scholars can model, simulate, and predict changes in the urban landscape using real-time data to produce the most realistic results, providing invaluable information for urban planners and governments to aim for a sustainable and healthy urban future.

Urban Rain Flood Models
The basis of studying urban rain and flood problems is to establish urban rain and flood models, calibrate and verify the models by simulating and reproducing historical flood events, and then provide technical support for urban hydrological forecasting, urban planning, and water resource utilization. The essence is to alleviate or even solve the problem of urban flood.

Urban Railway Network Centrality on Residential Property Values
Bangkok has experienced substantial investments in its urban railway network, resulting in a profound transformation of the city’s landscape. The network centrality analysis reveals that closeness centrality underscores the city’s prevailing monocentric structure, while the betweenness centrality measure envisions the potential emergence of urban subcenters.

Urban Public Food Procurement
Urban public food procurement can address malnutrition and improve the beneficiary experience at public institutions whilst reshaping food systems to be healthier and more sustainable. By developing, improving, and scaling public food procurement, urban governments in low- and middle-income countries (LMICs) can reach the most vulnerable whilst improving farmer livelihoods, creating business opportunities, and addressing environmental concerns.

Urban Parks Valued by Residents on Social Media
With the rise of the Internet, more and more people are recording and sharing their recreational experiences through social media platforms, which generates a large amount of real and effective data. Therefore, the use of big data technology to obtain information about people’s perceptions of park recreation offers the possibility for assessing environmental perceptions more comprehensively and objectively.
