“Understanding precedes action.” That is the motto of the Urban Observatory, an interactive installation and web app created by TED founder Richard Saul Wurman that compiled a wide range of urban data for over 150 cities, allowing users to compare various characteristics of those cities – from population density to traffic speed limits – side-by-side. Urban Observatory was first created in 2013, a banner year for news about urban big data; later that same year, Waag made headlines with its interactive map visualising the age of every building in the Netherlands. The emergence of such platforms allowed people to see the world around them in new ways.
With the rise of Google Earth and other GIS tools, and platforms like envelope.city, or environmental simulations based on digital twin models of cities, urban big data has quietly come to underpin a wide range of tools used by professionals who shape our cities, with both the amount of data collected and the influence it has over decision-making expanding dramatically. However, these advances typically happen behind closed doors and in undemocratic spaces. How long must we wait for software that has all the user-friendliness, accessibility, and appeal of those older platforms, but which provides the average person with the tools to shape their city? In other words, if “understanding precedes action”, then why after almost a decade are we not seeing big-data-driven apps that encourage the public to actually do something?
