ABSTRACT
With the emergence of new forms of geospatial/urban big data and advanced spatial analytics and machine learning methods, new patterns and phenomena can be explored and discovered in our cities and societies. In this special issue, we presented an overview of nine studies to understand how to use urban data science and GIS in healthcare services, hospitality and safety, transportation and mobility, economy, urban planning, higher education, and natural disasters, spreading across developed countries in North America and Europe, as well as Global South areas in Asia and the Middle East. The embrace of diverse geo-computational methods in this special issue brings forward an outlook to future GIS and Urban Data Science towards more advanced computational capability, global vision and urban-focused research.
Background
In the information age (Castells Citation1998), new forms of urban big data demand an in-depth understanding and diversified interpretation of human interactions with contemporary society. Urban Informatics (Shi et al. Citation2021) has surged as an interdisciplinary subject encompassing urban data science, informatics, GIS, various information and communication technology, big data analytics, smart cities, etc., and encourage people from academics, industry and public sectors to jointly explore the open data emerging in the context of urban environments (Foth, Choi, and Satchell Citation2011), such as social media data (Wang and Li Citation2021; Wang, Gerber, and Brown Citation2012; Chen, Cho, and Jang Citation2015), mobile data (Bogomolov et al. Citation2014; Ros’es, Kadar, and Malleson Citation2021), Geo-locational data (Kikuchi, Amemiya, and Shimada Citation2012; Hutt, Bowers, and Johnson Citation2021; Song et al. Citation2019; Tu et al. Citation2021), image data (Law et al., Citation2020; Woodworth et al. Citation2014; Liu et al. Citation2020) and video data (Ashby Citation2019; Lindegaard and Bernasco Citation2018). It has often been applied to visualize the digital information from the society we reside in, to interpret the human interactions with surrounding urban socio-economic environments, and to provide data-driven evidence for decision-making and industrial innovation.
In parallel boom of 21st century’s development of computer science and data visualization, GIS, geocomputation and urban analytics research methods, such as Kernel Density Estimation (KDE) (Bailey and Gatrell, Citation1995), geographically weighted regression (Cahill and Mulligan, Citation2007; Fotheringham, Brunsdon, and Charlton Citation2002), spatial autocorrelation and regression models (Anselin, Citation2009), spatio-temporal Bayesian modelling (Hu et al. Citation2018; Haining and Li Citation2020; Law, Quick, and Jadavji Citation2020), Risk Terrain Modelling (RTM) (Caplan, Kennedy and Mille Citation2011), etc., had been utilized widely in urban fields, such as healthcare accessibility (Kim, Byon, and Yeo Citation2018), services resilience especially against the pandemic (Li, Citation2021); urban safety and crime mapping (Hart, Lersch, and Chataway Citation2020), crime pattern detection (Chainey, Citation2020) aggregated at street segments (Tom-Jack, Bernstein, and Loyola Citation2019) and urban mobility (Sinclair et al. Citation2021: Sarim et al., Citation2021), hence brings forward the essentiality to apply such computational techniques in a geographically holistic sense. The special issue of Annals of GIS on GIS and Urban Data Science had compiled nine novel and original manuscripts demonstrating research on the main aspects of geo-informatics applications in urban contexts, in the hope of drawing follow-up inspirations towards further contributions to the literature.
Overview of this special issue
The articles included in this issue make significant contributions to the research in GIS and urban data science. These nine papers represent the diversity of urban data applications in different sectors, healthcare services (e.g. hospital services), hospitality and safety (e.g. Airbnb and crime), transportation and mobility (e.g. bike sharing), economy (e.g. retail business and labour force), urban planning (e.g. nightlight data), higher education (e.g. big scholarly data) and natural disasters (e.g. winter storm) across broad regions in North America, Europe and Asia, as depicted in . In combination of administrative data (e.g. Census) with the emerging forms of data such as bike sharing, airbnb, tweets, or night time light images, rich methods had been deployed including traditional (spatial) statistical or optimization methods such as OLS regression, GWR, and MCLP, as well as some advanced methods from GeoAI such as spatial clustering, travel pattern recognition, and text mining.
Outlook to the future
Computational methods and data sciences are transforming the conventional GIS into a new comprehensive discipline, with the notation of urban analytics, location intelligence, and more recently GeoAI (Janowicz et al. Citation2020; Kandt and Batty Citation2021). As showcased in the paper on this special issue, geospatial research has been applied in various applications, e.g. transport, retail, social interactions, using conventional methods, e.g. OLS regression; kernel density estimation and comparatively more recent computation methods, e.g. spatial network analysis and density-based spatial clustering methods. In pursuing further advancements in GIS and data, the next three sub-outlooks present a research agenda for achieving such objectives.
Advanced computational methods
A clearly pointed research direction is to build on the knowledge and skill around the different domains. We see how much GIS has been advanced by new computational methods and the ‘invasion’ of data science. This trend will continue, as the 5Vs of big data challenge the conventional GIS way of handling and analysing data. Moreover, domain knowledge becomes even more important to assist and solve real-world problems with the support of AI.
Global vision
The vast amount of data being generated around the world provides a unique opportunity for globally collaborative research and comparative studies of regions. Unlike in the old days, most research is based on locally generated data. Nowadays many data sets are available globally in a uniform format, for instance, Airbnb, Twitter, and Google mobility. It is now promising to promote the global research community and solve problems collectively. In particular, most of the research is in the context of developed countries and more attention needs to be given to the developing countries in the Global South and marginalized groups.
Urban focused research
As most of the world’s population is moving to cities (UN report, Citation2018), they also generate new urban challenges, e.g. social inequality, housing issues, ageing society, and health hazards. Data-driven methods have been proposed and demonstrated in this special issue to further tackle these problems, but more research and exploration need to be investigated to generate practical solutions and policy implementations for different urban issues.
