In 2021, the Google Research Africa team launched Open Buildings, an open-source dataset of building footprints across the Global South produced using AI and high-resolution satellite imagery. The team had a simple vision: to fill a major gap in data for population and density in the developing world. Now in its third version, their dataset contains polygons for 1.8 billion buildings over an area of 58 million km² in Africa, South and Southeast Asia, Latin America and the Caribbean. — Google
The data is useful in determining population size and other factors to solve urban density problems. Google's Research product manager Olivia Graham says: "About 2.5 billion more people could move to cities by 2050, most of them in the Global South — this could be a real step... View full entry
In the 18 months or so since dockless bike-share arrived in the US, the service has spread to at least 88 American cities. (On the provider side, at least 10 companies have jumped into the business; Lime is one of the largest.) Some of those cities now have more than a year of data related to the programs, and they’ve started gleaning insights and catering to the increased number of cyclists on their streets. — MIT Technology Review
Technology Review writer Elizabeth Woyke looks at ways how city planners in Seattle, WA and South Bend, IN use the immense stream of user-generated location data from dockless-bike-sharing programs to improve urban mobility — and how hackers could potentially access and abuse this (supposedly...

Sidewalk’s vision for Quayside — as a place populated by self-driving vehicles and robotic garbage collectors, where the urban fabric is embedded with cameras and sensors capable of gleaning information from the phone in your pocket — certainly sounds Orwellian. Yet the company contends that the data gathered from fully wired urban infrastructure is needed to refine inefficient urban systems and achieve ambitious innovations like zero-emission energy grids. — washingtonpost.com
Last fall Sidewalk Labs, a Google-affiliated company, announced plans to build a new smart city model on 12 acres of the Toronto waterfront named Quayside. The design would include infrastructure with sensors and data analytics with the claim of building an overall more streamlined, economical... View full entry
What if new technology further exacerbates urban inequality, especially among those on the wrong side of the digital divide? [Geographer Federico Caprotti of the University of Exeter] sees the world heading toward a notion of a “new urban citizen”, one that continually provides data, which may leave out those who are unable or unwilling to contribute. — Citiscope
Citiscope interviews geographer and smart-city researcher Federico Caprotti, who co-wrote an academic paper in response to the U.N.'s approval of the New Urban Agenda last year. Caprotti shares his thoughts on the rise of the “new urban citizen”, as well as the hidden inequalities that... View full entry
Copenhagen has become the first city in the world to attempt to monetize its, and others’, data through a city data market.
Traffic snarl-ups, home break-ins, whether it rained or snowed, and how much electricity the city dwellers use each day is among the data to be traded for cash, city officials announced. Interestingly, the city, which is partnering with Hitachi on the project, also wants to incorporate others’ data.

"Not all data will have a price tag—some of it will be free, but it will be anonymized anyway."Relatedly, in a recent conversation with Joseph Grima, co-founder of Space Caviar, the architect suggested, "...the home is becoming a factory of data to the point that one could pay one's rent through...
