A Framework for Optimizing Open Spatial Data in Urban Planning and Policy Applications

It is well-known that remote sensing technology has played a very important role in the urban planning and management since 1980s. In the past thirty years, as one of spatial data sources, remote sensing datasets, which contain more information of earth surface as compared with usual urban maps, have been used in urban planning and management in China. With the development of remote sensing technology such as the high spatial resolution sensors, 3D laser scanning, data mining and advanced image processing technology, remote sensing can be widely used in the whole range of urban planning processes. In this paper, we firstly make a review of the urban remote sensing applications in urban study and planning by giving examples. Then we identify remote sensing applications in different urban planning stages including master planning, district planning, detailed planning and planning implementation as well as in urban studies. We also analyze the bottlenecks of the remote sensing applications in urban planning and management in China at the end.

Risk assessment along the gas pipelines and its application in urban planning

With the rapid development of industry in China, the number of establishments that are proposed or under construction is increasing year by year, and many are industries that handle flammable, explosive, toxic, harmful, and dangerous substances. Accidents such as fire, explosion, and toxic diffusion inevitably happen. Accidents resulting from these major hazards in cities cause a large number of casualties and property losses. It is increasingly important to analyze the risk of major hazards in cities realistically and to suitably plan and utilize the surrounding land based on the risk analysis results, thereby reducing the hazards. A theoretical system for risk assessment of major hazards in cities is proposed in this article, and the major hazard risk for the entire city is analyzed quantitatively. Risks of various major accidents are considered together, superposition effect is analyzed, individual risk contours of the entire city are drawn out, and the level of risk in the city is assessed using "as low as reasonably practicable" guidelines. After the entire city's individual risk distribution is obtained, risk zones are divided according to corresponding individual risk value of HSE, and land-use planning suggestions are proposed. Finally, a city in China is used as an example to illustrate the risk assessment process of the city's major hazard and its application in urban land-use planning. The proposed method has a certain theoretical and practical significance in establishing and improving risk analysis of major hazard and urban land-use planning. On the one hand, major urban public risk is avoided; further, the land is utilized in the best possible way in order to obtain the maximum benefit from its use.

<p>Urban spatial planning as a part of spatial planning activities actually is a form of public policy formulation related with urban space management. Actions done by the policy actor in the formulation process of public policy will be extremely determined by the perspectives used. Governance as the main perspective in public administration and management demands the application of principles which attributed to it in order to achieve good governance. Based on that, the problem of the research is: how is the priority of the governance principles related to the actor/agent involved in urban planning? The purposes of the research are to know, to describe, and to analyze the priority of governance principles related to the actor/agent involved in urban planning. The type of the research, basically, is a descriptive research using the quantitative model analysis, that is Analythical Hierarchy Process. Data sources are taken from the research respondents which are consisting of municipal government elements; civil society and private (business) sector.</p>The result shows that the priorities of governance principles application in urban planning based on the involved actor/agent are: <em>first</em>: participation (3.141); <em>second</em>: responsive (3.021); <em>third </em>: transparancy (3.009); and <em>fourth </em>: accountability (2.867), with the actors value: civil society (1.168); municipal government (1.096); and business (private) sector by the value of (0.736) respectively. Civil society participation is done to the whole phases of urban planning in the form of providing data and information, opinion and aspiration, as well as objection and rebuttal toward the concept of city territorial development. Meanwhile, practically, the research recommends the need of regulation toward the civil society participation in urban planning in local nature to find the best practice; the application of governance principles should become the mindset of public officer and the planner in spatial planning.

The Other Battle of Algiers

Understanding the complexity of urban systems remains a significant challenge for researchers and practitioners in urban planning and governance. Cities function as multifaceted systems composed of interconnected subsystems with nonlinear interactions, making the design of effective interventions to enhance sustainability and liveability particularly challenging. Spatial modelling has gained prominence in recent decades, fuelled by advances in digital technologies and the advent of digital twins as decision support tools. To fully harness these innovations, it is essential to grasp their underlying principles, strengths, and limitations, and to select the most suitable modelling approach for specific applications. This paper examines two contrasting spatial modelling paradigms: top-down and bottom-up. Specifically, it focuses on Space Syntax and Agent-Based Modelling as representative tools of each approach, analyzing their potential applications in urban planning. This discussion delves into the effectiveness of the proposed methodologies in analyzing crime dynamics—selected as a representative application field—at the micro-urban scale. It highlights the insights each approach offers, emphasizing their contributions to understanding the spatial and environmental factors influencing crime patterns. Finally, this paper explores the potential for integrating these methodologies to develop hybrid models that capture both spatial structure and emergent behaviours, offering enhanced support for sustainable urban policies and planning.

<p style="text-align: justify;">This study explores the use of simulated natural drainage systems for sustainable urban landscape planning to address flood disasters in low-lying urban areas. Traditional drainage methods lack sustainability, whereas simulated natural drainage systems, such as green infrastructure, rain gardens, and wetland parks, can enhance urban flood resilience and environmental quality through scientific design and strategic layout. In San Francisco, the issue of flood disasters in low-lying areas has become increasingly severe, with traditional drainage systems struggling to effectively manage flood risks under extreme weather conditions. This study employs R programming to simulate natural drainage systems, evaluating their effectiveness in mitigating flood disasters and improving ecological environments. By utilizing rainfall data, topographic data, and drainage system data from San Francisco, a simplified hydrological model was constructed to calculate catchment areas and runoff, simulating the effects of natural drainage systems. Results indicate that natural drainage systems significantly reduce flood risks and enhance ecological benefits. The findings provide urban planners with new flood management strategies, emphasizing the importance of integrated management and systemic thinking, and highlight the future potential for widespread application in urban planning. By integrating landscape design with water resource management principles, this study proposes a systematic solution validated through case studies in different cities, demonstrating its feasibility and effectiveness. This research offers new insights and methods for urban flood control engineering and landscape planning, contributing to enhanced urban disaster resilience and improved urban living environments. The simulation of natural drainage systems facilitates sustainable urban development, providing valuable references for the advancement of sustainable urban landscape planning.</p>

Most data related to urban and regional planning and the assessment of economic, environmental and social sustainability of a city or region have a spatial component. Some of these data are also inherently ambiguous in nature. Traditional Boolean logic in GIS lacks the capability to model the fuzziness, uncertainties and imprecision of data in geographic information and human decision-making processes. While considerable studies have investigated applications of fuzzy system in urban planning, only a few studies have attempted to integrate fuzzy inference within a GIS platform with the Mamdani method. To facilitate the efficient modelling and displaying of the imprecision of geographic data and human judgement, we develop a rule-based fuzzy inference system within ArcGIS environment using the Sugeno method. This article describes the development process of the system and demonstrates the usefulness of fuzzy logic application in urban planning. It concludes with a discussion of implications for urban planning and needs for further research.

Chinese cities are becoming larger and urbanization is accelerating with the rapid development of China's economic construction and formulation of planning objectives. Traditional manual management and information processing methods cannot satisfy the requirements of modern urban planning management. Thus, this study analyzes the application of geographic information system (GIS) in urban planning, starting with the characteristics of GIS technology. Structured analysis and design are conducted for urban planning and the location system. The software engineering approach is adopted throughout the entire process, from the survey to the overall design of the system and database. The evaluation factors of the pension facilities in Baohe, Hefei are extracted through the factor evaluation method, and the weight value is determined. The GIS analysis method is then used, and site suitability evaluation is performed on the Baohe district land layout. Results show that the application of urban planning and a location system based on GIS technology can provide the basis for urban planning.

This paper will consider the significance of recognising – and researching – the linguistic diversity within contemporary cities in Europe in particular, and other parts of the world more generally. It will argue that failure to take linguistic diversity – and linguistic identity – seriously has limited analysis, diagnosis, and prescription in urban planning and urban policy. Currently, a heightened attention to cultural difference, of which linguistic diversity is a central feature, is re-shaping the social fabric of cities of all sizes and in all parts of the world. This is reflected in new, or re-newed, forms of cultural identity, of cultural division in urban labour markets, of political mobilisation, of conflict and cohesion .These changes need to be better understood by urban policy and planning (and, indeed,by language planning). The paper is organised around four inter-related topics identified as key dimensions of current discussions of city life, its tensions and potential: • identity and the city • citizenship • sustainable diversity and social cohesion • urban governance, policy and planning
