Using AI to Map Africa and Beyond
Did you know that by 2050, the world’s urban population is expected to grow by 2.5 billion, with nearly 90% of that growth happening in cities across Africa and Asia? To keep up with this rapid urbanisation, governments, humanitarian organisations, and researchers need accurate information on buildings and infrastructure.
This data helps plan for future growth, respond to crises, and ensure resources are distributed fairly. But in many parts of Africa and the Global South, this vital information is outdated or simply unavailable.
That’s why Google launched the Open Buildings project in 2021. It started at the AI Research Lab in Accra, Ghana, and has helped map 1.8 billion buildings across Africa, Asia, Latin America, and the Caribbean—about 40% of the globe. This data has been used by governments, NGOs, and researchers to improve services and respond to disasters.
Real-world examples:
In Uganda, the nonprofit Sunbird AI used our data to prioritise areas for rural electrification, ensuring that towns and homes most in need received power first.
WorldPop, a team from the University of Southampton, has integrated the Open Buildings data into their population estimates. These estimates are being used by UN agencies and governments, including in Nigeria, where the data has helped identify areas where children haven’t received routine immunizations.
Now, we’re expanding this effort with the Open Buildings 2.5D Temporal Dataset, which doesn’t just map buildings—it shows how they change over time and estimates their heights. This new data covers the years 2016 to 2023, offering a detailed picture of how cities and settlements across Africa and the Global South have grown. This is crucial for urban planning, disaster response, and understanding population density.
Governments and organisations can use this data in various ways:
Flood preparedness: In flood-prone areas, accurate data can help authorities predict which buildings and neighbourhoods are most at risk.
Urban growth: In cities like Kumasi, Ghana, which has seen rapid expansion, this data allows city planners to better manage resources and infrastructure.
Disaster recovery: In places like Palu, Indonesia, where a tsunami struck in 2018, this data shows how the built environment changed before and after the crisis, helping rebuild communities more effectively.
How we built this dataset:
We used AI to improve the quality of low-resolution satellite images and estimate the size and height of buildings. This is important because higher-resolution satellite images are not always available for the Global South. With this technology, we’ve created a detailed map of over 58 million square kilometres, covering parts of Africa, Latin America, South, and Southeast Asia.
Why this matters:
Maps are a lifeline. They help governments, humanitarian agencies, and researchers ensure that everyone is counted and represented. With this new dataset, we’re giving these organisations better tools to plan for the future, respond to crises, and support communities in need.
We invite researchers, policymakers, and anyone interested in urban development to explore the Open Buildings 2.5D Temporal Dataset on Google Earth Engine and share their feedback with us.
National Identity Management Commission (NIMC) of Nigeria has launched a new digital identity verification tool called the NIN Authentication (NINAuth) application.
The initiative, which forms part of President Bola Tinubu’s Renewed Hope Agenda, aims to strengthen the country’s national digital identity management framework.
The launch builds upon Nigeria’s comprehensive unified digital identity system that has been transforming access to financial services and government programs.
The NINAuth application introduces several key features focused on data security and privacy.
The platform requires explicit user consent before sharing identity information for Know Your Customer (KYC) processes, giving individuals greater control over their personal data.
The system provides seamless access to various government services, including SIM card registration, immigration applications, passport processing, tax filings, and financial transactions.
The development follows significant investment in Nigeria’s digital identity infrastructure, including a $45.5 million support from the World Bank as part of the Digital Identification for Development (ID4D) project.
As the official service for integration with NIMC’s backend infrastructure, NINAuth enables secure verification processes across ministries, departments, and agencies (MDAs).
The application is available for download on both the Google Play Store and Apple iOS App Store for users of the National Identification Number (NIN).
The rollout represents a significant milestone in Nigeria’s ongoing efforts to digitize government services and strengthen identity verification processes.
“NINAuth is a cutting-edge suite of services including web, API, and mobile verification designed to enhance data security, protect privacy, and simplify access to government services,” said Dr. Kayode Adegoke, Head of Corporate Communications at NIMC.
“The platform introduces a robust layer of protection, empowering individuals with greater control over their personal information.”
The implementation supports the objectives of the recently established Nigeria Digital Identification for Development Project Ecosystem Steering Committee, which oversees the country’s digital identity initiatives.
President Bola Ahmed Tinubu has approved the launch of the NINAuth app and directed its use for verification and authentication across all MDAs.
The application provides a secure single sign-on solution for accessing government services and social protection programs while maintaining strict data privacy controls.
The centralized approach to digital identity management represents a significant step forward in Nigeria’s digital transformation journey and its commitment to modernizing government services.
Nigerian Copyright Commission (NCC) has set in motion a machinery to checkmate the booming copyright piracy market in the country.
Copyright piracy is said to cost Nigeria an annual loss estimated at billions of naira.
Despite the absence of a coordinated or official statistics to gauge the quantum of loss, John Asein, director general, NCC, said as far back as 2019, Nigeria lost N918 trillion ($3 billion) annually to digital piracy.
The financial damages severely impact local businesses and innovation efforts.
The commission, in collaboration with the World Intellectual Property Organisation (WIPO), has started a project to develop strategies and tools to address the menace.
Speaking at a stakeholders’ meeting on the WIPO project to address online copyright piracy in Nigeria, Asein said digital technologies have unlocked tremendous opportunities for the creative and innovation sectors.
The NCC boss said technology also poses serious challenges, including online piracy, which he said is growing rapidly.
He said: “Pirate sites continue to emerge rapidly, with statistics indicating a 6.7 per cent increase in user visits. A significant percentage of these users are students aged between 18 and 24, with social media and messaging platforms becoming major gateways for accessing pirated content.”
He added: “No industry is immune. The most affected sectors include television (43.6 per cent), publishing (27.5 per cent), film (12.9 per cent), music (7.0 per cent), and software (6.2 per cent).
“Far beyond mere statistics, the victims are no longer only foreign right owners. Many Nigerians in these sectors have also been bruised and their creative enterprises ruined.”
Nigerian Postal Service (NIPOST) has signed an international mail partnership with KLM Royal Dutch Airlines for improved delivery access to over 200 countries without middlemen.
Tolani Odeyemi, postmaster-general and chief executive officer of NIPOST, described the deal as a “major milestone” for the country’s logistics and postal sector.
In a statement on X on Monday, Odeyemi explained that the new agreement marks NIPOST’s first direct international airline partnership for several years.
“For a long time, NIPOST operated without any direct partnerships with international airlines, relying heavily on multiple third-party handlers,” the Postmaster-General stated. This often resulted in delays, higher costs, and uncertainty around the delivery of packages.”
She explained that under the new arrangement, KLM will directly handle all outbound international mail from Nigeria, eliminating the need for intermediaries.
“This translates to faster and more reliable delivery, reduced risk of loss or damage, lower handling charges, and access to over 200 countries through KLM’s global network,” the Postmaster-General stressed.
According to Odeyemi, NIPOST’s breakthrough came after it began settling long-standing debts owed to international carriers, a step she said was key to “rebuilding global trust” in Nigeria’s postal system.
She revealed that talks were also ongoing with Ethiopian Airlines to bolster regional and continental logistics, particularly on African and Eastern routes.
“Our goal is clear and unwavering: to connect Nigeria regionally and globally, efficiently, securely, and affordably,” Odeyemi asserted.
The NIPOST CEO described the development as a significant win for Nigerian businesses and small and medium-scale enterprises that rely on international shipping, stating, “You now benefit from quicker, more affordable international shipping, greater peace of mind with improved reliability, and new potential to reach and grow in global markets.”
Odeyemi commended the teams behind the scenes and pledged continued improvements in service delivery, adding that the deal signals a turning point for the agency.
