Qingdao develops advanced 3D “city map” to enhance smart urban management

Published

By Wang Zhe, People’s Daily

With a simple scroll of the mouse, the city of Qingdao, east China’s Shandong province, comes vividly into view – high-resolutionbuildings rise sharply, their intricate details clearly rendered.

At his workstation, Hu Zhenbiao, chief systems architect at the Qingdao Institute of Survey and Mapping, introduced a city-scale 3D simulation platform: a full-scale digital twin of the city.

Real-scene 3D modeling has become a vital strategic resource and production element in the development of digital cities and the broader digital economy. By offering accurate, spatial-temporal depictions of urban spaces, these technologies provide vital insight into the dynamics of modern city life, infrastructure, and ecosystems.

The platform, officially launched in March 2021 under the leadership of the Qingdao Institute of Survey and Mapping, represents a landmark in urban digitization.

“Behind this platform lies more than six months of aerial photography, the processing of millions of images, and the 3D modeling of hundreds of thousands of buildings,” Hu explained.

Qingdao’s varied topography – marked by hilly terrain and dramatic elevation changes – necessitated the use of oblique aerial imaging to capture raw imagery and build an accurate 3D model.

For this phase, the project team deployed manned fixed-wing aircraft equipped with 150-megapixel, five-lens oblique aerial cameras. The aerial survey covered the entire urban area, achieving a ground resolution of 15 centimeters and maintaining more than 70 percent image overlap to maximize accuracy.

Hu noted that certain structural details – such as eaves and building undersides – were sometimes difficult to capture due to limited aerial angles, requiring on-site supplemental photography. “We used a combination of hybrid restoration and modeling techniques to accurately reconstruct the structures,” he said, pointing to the Qingdao International Conference Center on his screen. “Those eaves, for example, were recreated using 3D modeling.”

In March 2022, following expert review, the project was officially launched for citywide application. Today, the platform covers Qingdao’s entire land area – 11,000 square kilometers – as well as 800 kilometers of coastline, 49 bays, and seven inhabited islands.

“Fire reported on the eastern slope. Please respond immediately,” came the voice over the radio at the emergency command center in Qingdao’s West Coast New Area.

Qi Degang, deputy headof the area’s emergency management bureau, responded quickly. “The nearest water source is Reservoir No. 37 in Lingshanwei, about 700 meters away.”

This exchange occurred during a forest fire response drill on Xiaozhu Mountain. Displayed prominently on a large screen in the command center was a real-time, 3Dforest fire map – showing the fire’s location, affected area, and smoke direction.

“Our drones send back live footage, which is directlyfed into the 3D platform,” explained Mu Kun, head of forest fire response at the emergency management bureau.

A new call came in: “There’s a fork ahead – what’s the fastest route?”

Mu quickly zoomed in, selected a mountain trail and charted a path for the responders. “This trail is only one meter wide. Rescuers will have to go on foot. Elevation gain: 200 meters.”

“The 3D model allows us to act with greater speed and precision,” Qi added. “It helps us identify access routes, calculate burn areas, and direct field personnel efficiently.”

To date, Qingdao’scity-scale 3D simulation platform has been shared with over 60 municipal departments. It supports more than 100 key functions, including disaster prevention and mitigation, urban planning, social governance, and urban renewal. The platform also underpins over 70 digital government service applications and records nearly 100 million uses annually.

“Compared to traditional 2D maps, 3D modeling offers greater realism, dimensionality, and accuracy,” said Xue Hongli, deputy head of the Qingdao Bureau of Natural Resources and Planning. “It creates a holographic digital twin of the physical world, providing strong spatial support for fine-grained urban management.”

Xue emphasized that cities are constantly changing and 3D mapping must evolve in tandem to capture these transformations with fidelity.

At the bureau’s headquarters, staff members examined two versions of a digital model for a former mining site in Qingdao’s West Coast New Area. The comparison revealed tangible signs of ecological restoration – more vegetation and a gentler slope.

Qingdao is home to 898 legacy mine sites. In the past, inspectingthese sites required a full month of on-the-ground efforts. Now, with the help of the 3D model, the same work takes just five days. Since 2023, the city has carried out annual temporal updates to the city-scale 3D simulation platform, enabling it to track urban changes with precision and support data-driven analysis and evidence-ba

SANKARA NIGERIA LIMITED PARTNERS LOVOL TO EMPOWER AFRICAN YOUTHS THROUGH MECHANIZATION TRAINING IN KADUNA

Published

on

In a bold step toward tackling youth unemployment and advancing agricultural mechanization in Nigeria and across Africa, Sankara Nigeria Limited, in partnership with LOVOL, has successfully launched an intensive training programme aimed at equipping young people with modern mechanical and technical skills.
The initiative, which focuses on contemporary mechanized systems and agricultural equipment maintenance, is designed to build a new generation of skilled technicians capable of driving Africa’s agricultural transformation. The programme provides hands-on training in modern mechanical practices, particularly in the operation, servicing, and maintenance of advanced farming machinery.
Speaking on the development, Dr. Nafiu Danladi Sankara described the opportunity as both impactful and timely, noting that the programme represents a strategic investment in human capital development. According to him, the collaboration between Sankara Nigeria Limited and LOVOL underscores a shared commitment to empowering African youths with practical knowledge that fosters self-reliance and reduces dependence on white-collar employment.
He emphasized that the training is not limited to Nigeria alone but extends across Africa, reflecting a broader vision to create a continent-wide network of competent technicians who can support the growing demand for mechanized farming solutions.
“This initiative is about more than training; it is about creating opportunities, restoring dignity to labour, and building a future where young people can stand on their own through acquired skills,” he stated.
The technical workshop, which drew participants from different parts of the region, was held in Kaduna State, specifically in Zaria, at Unguwa Kaya Junction, New Jos Road, KM 2.
Participants in the programme expressed appreciation for the quality of training and the exposure to modern equipment, noting that such initiatives are critical in bridging the skills gap in the agricultural and mechanical sectors.
The programme also received warm support from the host community in Zaria, located in the historic Zazzau Emirate, where participants were welcomed with remarkable hospitality. Organizers and trainees alike commended the people of Zaria for their generosity and encouraging reception, which contributed to the overall success of the exercise.
As Nigeria continues to seek sustainable solutions to unemployment and food security challenges, initiatives like this stand as a testament to the role of private sector collaboration in national development. By equipping young people with relevant, market-driven skills, Sankara Nigeria Limited and LOVOL are not only transforming lives but also laying a solid foundation for economic growth and agricultural modernization across the continent.

…Orders Ojulari-led management to produce Kyari, others before committee

From Taiye Hassan
The Senate, on Wednesday, through its Committee on Public Accounts, fixed April 29, 2026, as the deadline for the management of the Nigerian National Petroleum Company Limited (NNPCL) to appear before it and account for the alleged N210 trillion flagged in audit reports covering 2017 to 2023.
The committee directed the Group Chief Executive Officer (GCEO) of NNPCL, Engineer Bayo Ojulari, to appear alongside the immediate past GCEO, Mele Kyari; former Chief Financial Officer, Umar Ajia; Dr. Bala Wunti; and the company’s external auditors on the scheduled date without fail.
The resolution followed a motion moved by Senator Osita Izunaso (Imo West) and seconded by Senator Adams Oshiomhole (Edo North).
Chairman of the committee, Senator Aliyu Wadada (Nasarawa West), stressed that the N210 trillion in question, as contained in the audit reports, must be fully accounted for by the company’s management, particularly the immediate past leadership led by Kyari.
According to him, the responses so far provided by NNPCL to the 19 audit queries were unsatisfactory, noting that Nigerians deserve clear, detailed, and transparent explanations.
“This committee, and by extension the Senate, is not satisfied with the blanket explanation given by NNPCL on the N103 trillion it claimed represents liabilities. Liabilities comprise components such as retention fees, legal fees, and audit fees, and the specific amounts spent on each must be clearly stated and justified,” he said.
Wadada also demanded a detailed breakdown of the N107 trillion which the company claimed was expended on Joint Venture (JV) cash calls, as well as funds allegedly owed by some defunct banks whose identities were not disclosed.
“Consequently, it is hereby resolved that NNPCL is given an additional two weeks to appear before this committee unfailingly. The deadline for compliance is Wednesday, April 29, 2026,” he added.
Earlier, a member of the committee, Senator Abdul Ningi (Bauchi Central), called for the invocation of the National Assembly’s powers to compel the appearance of NNPCL management, citing repeated failures to honour invitations.
“We must treat this matter with the utmost seriousness. The essence of democracy rests significantly on the strength and authority of the legislature. Unfortunately, in recent times, there appears to be a growing reluctance by individuals to honour invitations from the National Assembly, leaving members feeling helpless in compelling appearances before committees,” he said.

Stephen Olufemi Oni, Ilorin

A frontline political group in the All Progressives Congress (APC) in Kwara State have charged political actors across the 16 local government areas of the State to shun violence, rancour and hate speech before, during and after the 2027 general elections.

The APC group, under the aegis of the Asa Progressive Movement (APM), has, therefore, sued for peaceful, issue-based campaigns, devoid of acrimony and name-calling, ahead of the elections.

The Movement made this call in Afon, headquarters of the Asa local government at the endorsement programme of President Bola Ahmed Tinubu for second term, as well as the governorship ambition of former Kwara State APC Chairman, Hon. Bashir Omolaja Bolarinwa.

In a communique signed by the APM Coordinator and the Secretary, Engineer Daud Oladipupo Babatunde and Comrade Yusuf Mutiu Akorede respectively, the Movement said: “We are committed to a peaceful, issue-based campaign and we, therefore, urge all political actors to shun violence, hate speech, and any conduct capable of heating up the polity.

“We call on all well-meaning sons and daughters of Kwara State, regardless of party affiliation, to join this movement for the restoration and advancement of our dear State.

“The 2027 election is about the future of our children and we must rise above petty sentiments.

“We pass a vote of confidence in Hon. Bashir Omolaja Bolarinwa and in the leadership of our great party, the APC, for presenting to the people a competent, credible, and compassionate candidate.

“All structures of the Movement, from the State to the polling unit levels, are hereby directed to commence immediate and intensive mobilisation for the reelection of President Bola Ahmed Tinubu and the candidature of Hon. Bashir Omolaja Bolarinwa. Every member is now an ambassador of these two projects.”

The communique reads further: “Our decision is predicated on Hon. Bolarinwa’s proven track record of service as former Councillor, former Council Chairman, former member of the Federal House of Representatives, former State Chairman of the party, who led the party to 100 percent victory in the 2019 elections, and former Board Chairman of the NBC; his desire to tackle the lingering problems of insecurity, youth unemployment, and agricultural revival; and his integrity, accessibility, and capacity to unite the diverse peoples of the State.

“The APM unanimously endorses Tinubu for second term and Bolarinwa as our preferred candidate for the office of Governor in the 2027 general elections under the platform of the All Progressives Congress (APC).”
