Smart city
Urban dashboards
Digital twins
Big data vs. just data
The digital technologies approach
Urban infrastructure and services are managed computationally
Networked digital instrumentation embedded into the urban fabric
Continuous streams of data that dynamically feed into management systems and control rooms
New forms of governmentality
Based on Kitchin (2019)
The outputs approach
Strategic use of information and communications technology (ICT)
➔ smarter citizens, workers, policy, and programs
➔ innovation, economic development, and entrepreneurship
➔ urban resilience and sustainability
Based on Kitchin (2019)
The people-centric approach
ICT-led, citizen-centric model of development
➔ social innovation and social justice, civic engagement and activism
➔ transparent and accountable governance
Based on Kitchin (2019)
In reality…
… a blend of all these approached
Rio de Janeiro, Brazil: The first smart city
(Smart) cities generate much more data nowadays
Local authorities are under pressure to release open data for:
public scrutiny
civic apps
Data reuse:
internally facing
externally facing
A visual display of the most important information needed to achieve one or more objectives; a consolidated and arranged on a single screen so the information can be monitored at a glance (Few and Edge 2007)
Transparency, open government philosophy, accountability (Young, Kitchin, and Naji 2022)
Improve user’s ’span of control of large and complex data
Share outputs
Not just neutral, technical tools
Translators and engines rather than mirrors
Reductive in nature (vs. the complex nature of cities)
Decontextualize cities (Kitchin, Maalsen, and McArdle 2016)
A mirror image of a physical process that is articulated alongside the process in question, usually matching exactly the operation of the physical process which takes place in real time
A variety of digital simulation models that run alongside real-time processes that pertain to social and economic systems as well as physical systems
Models are simplifications not replications of the real thing

Difference in volume, variety, velocity, complexity, and potential value
Big Data - large - complex - constantly changing
Just Data - small - structured - static
Big Data - Digital traces human activities leave behind - Accidental (Arribas-Bel 2014) - Geospatial technologies [important for urban researchers] - Fine-grained in resolution - Flexible
Just Data - Collected for purpose - Low-grained resolution - Less-flexible
API’s - way to access big data
