Special Issue Information

Dear Colleagues,

Cities play a pivotal role in the pursuit of sustainable development, public health, and resilience in the face of dynamic challenges like climate change, (non-)communicable disease and food security. Geospatial analytics, an interdisciplinary field at the intersection of geography, data science, and urban planning, provides a powerful framework for understanding and addressing these critical urban issues. The importance of geospatial analytics in advancing sustainable, healthy, and resilient cities cannot be overstated. It enables researchers and policymakers to harness the power of spatial data and advanced analytics to gain insights into complex urban systems, inform evidence-based decision-making processes, and design effective interventions.

With this in mind, we are pleased to announce the launch of a Special Issue on ‘Geospatial Analytics for Sustainable, Healthy and Resilient Cities.’ This Special Issue aims to bring together cutting-edge research that utilizes geospatial analytics to address the diverse challenges faced by cities worldwide. It provides a unique platform for sharing innovative methodologies, empirical studies, and theoretical advancements that contribute to the advancement of urban sustainability, public health, and resilience. By highlighting the role of geospatial analytics in urban contexts, this Special Issue aims to foster a deeper understanding of the spatial and temporal dynamics shaping cities, while promoting the use of geospatial data and analytical techniques to inform urban policy, planning, and design.

This Special Issue invites researchers and practitioners from various disciplines to submit their original research articles and reviews, providing novel insights into topics focusing on, but not limited to, the following:

Sustainable urban mobility and accessibility;
Active and healthy communities;
Sustainable transport in cities;
Spatial-temporal analysis of noise and air pollution;
Urban heat monitoring and mitigation;
Geospatial analytics for travel behavior and physical activities;
Promotion of sustainable and equitable food access;
Environmental health inequality and spatial justice;
Spatial analysis of urban infrastructure;
Geospatial approaches to urban land use and urban growth modeling;
Spatial analysis of social vulnerability and equity in urban contexts;
Remote sensing for urban infrastructure and utilities;
Remote sensing for urban resiliency;
Geospatial analytics for equitable urban planning and governance.

We look forward to receiving your contributions.

Sincerely,

Dr. Dong Liu

Sales in Commercial Alleys and Their Association with Air Pollution: Case Study in South Korea

Abstract

We investigate the dynamic interplay between air pollution (PM₁₀) and income and their joint association with quarterly sales in commercial alleys, focusing on the pre-COVID-19 (2018–2019) and COVID-19 (2020–2021) periods in Seoul, South Korea. The objective of this study is to identify how air pollution and income collectively influence consumer spending patterns by looking at the increase and decrease in sales in commercial alleys, with a focus on contrasting these effects before and during the COVID-19 pandemic, utilizing advanced machine learning techniques for deeper insights. Using machine learning techniques, including random forest, extreme gradient boosting, catboost, and lightGBM, and employing explainable artificial intelligence (XAI), this study identifies shifts in the significance of predictor variables, particularly PM₁₀, before and during the pandemic. The results show that before the pandemic, PM₁₀ played a notable role in shaping sales predictions, highlighting the sensitivity of sales to air quality. However, during the pandemic, the importance of PM₁₀ decreased significantly, highlighting the transformative indirect impact of external events on consumer behavior. This study also examines the joint association of PM₁₀ and income with sales, revealing distinctive patterns in consumer responses to air quality changes during the pandemic. These findings highlight the need for dynamic modeling to capture evolving consumer behavior and provide valuable insights for businesses and policymakers navigating changing economic and environmental conditions. While this study’s focus is on a specific region and time frame, the findings emphasize the importance of adaptability in predictive models and contribute to understanding the complex interplay between environmental and economic factors in shaping consumer spending behavior.

Abstract

Urbanization has led to environmental challenges, with the urban heat island effect being a prominent concern. Understanding the influence of urban environmental characteristics (UECs) on land surface temperature (LST) is essential for addressing this issue and promoting sustainable urban development. The spatiotemporal characteristics and influencing factors of LST have been investigated in past studies, but research that explicitly investigates the key factors and long-term spatial relationships affecting LST in city-scale urban areas is limited. Remote sensing techniques provide valuable insights into LST patterns and the relationship between urban environment and temperature dynamics. We utilized Landsat 8 images to derive the LST and six spectral indices from 2017 to 2022 in Hong Kong, a city characterized by high population density and rapid urban growth. We also acquired land use data to reflect Hong Kong’s dynamic urban landscape. The complex interactions between urban environment and LST were analyzed using various analytical techniques, including slope trend analysis, land use change detection, and correlation analysis. Finally, we constructed a random forest model to assess the importance of each environmental characteristic. Our findings provide three key insights for regions experiencing rapid urbanization. First, the LST showed an increasing trend in Hong Kong from 2017 to 2022, with the annual LST rising from 21.13 °C to 23.46 °C. Second, we identify negative relationships between LST and vegetation (−0.49)/water bodies (−0.49) and a positive correlation between LST and built-up areas (0.56) utilizing Pearson’s correlation. Third, the dominant influence of built-up areas was underscored, contributing as much as 53.4% to elevated LST levels, with specific attention to the substantial reclamation activities in Hong Kong. The insights from this study provide valuable guidance for policymakers, urban planners, and environmental researchers to formulate evidence-based strategies to achieve a resilient, livable urban future.
