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

The Nigeria Customs Service, Kwara Area Command, has received commendation from the Assistant Comptroller-General of Customs and Zonal Coordinator for Zone ‘B’, Nsikan Patrick Umoh, for maintaining a clean operational record and upholding professionalism in the discharge of its duties.

ACG Umoh gave the commendation during an oversight visit to the Command’s headquarters in Ilorin as part of her tour of operational commands within the zone.

Addressing officers and men of the Command, Umoh was excited that since she assumed office, her headquarters had not received any adverse report against the Kwara Area Command.

She said the record was a reflection of the discipline, integrity and professionalism demonstrated by personnel in their daily operations.

“I want to commend the leadership and personnel of the Kwara Area Command for their exemplary conduct, discipline and dedication to duty,” she said.

The Customs boss, who delivered the goodwill message of the Comptroller-General of Customs, Bashir Adewale Adeniyi, MFR, urged officers to maintain high standards of professionalism both on and off duty.

She warned personnel against involvement in illicit drugs, sharp practices and other activities capable of tarnishing the image of the Service.

Umoh also called on officers to strengthen unity and teamwork, describing the Service as one family working towards a common goal. She assured them of the continued support of the zonal and Service headquarters.

Earlier, the Acting Area Controller of the Command, Deputy Comptroller Najeem Akanmu Ogundeyi, highlighted the major achievements, operational milestones and administrative successes recorded under his leadership.

The visit also featured an interactive session between the Zonal Coordinator and major trade stakeholders, including representatives of freight forwarding associations, the Manufacturers Association of Nigeria (MAN), and major excise factories such as ITC and SANICA.

During the engagement, Umoh commended the existing relationship between the Command and the business community, while responding to concerns surrounding cargo clearance procedures, examination timelines and regional trade competitiveness.

The stakeholders also received clarifications on issues affecting their operations, with the Customs official assuring them of the Service’s commitment to facilitating legitimate trade.

The oversight visit ended with an inspection of the Command’s administrative offices, warehouse and residential barracks.

Umoh expressed satisfaction with the level of orderliness, environmental cleanliness and discipline observed across the facilities.

The Command said the visit further reinforced its commitment to professionalism, trade facilitation and effective service delivery in Kwara State.

OUR LAND IS NOT FOR SALE, CATHOLIC PRIESTS TELL FG

Published

on

By our Correspondent

The Nigeria Catholic Diocesan Priests Association (NCDPA), Makurdi Diocese, has strongly rejected the decision of the Federal Government to include Benue State in the pilot implementation of its National Ranching Policy.

The association said it was particularly concerned that Benue State, which it described as an already bleeding and targeted state, was included in the policy, which is initially kicking off at the Wase Grazing Reserve in Plateau State.
In a statement signed by its Chairman, Rev. Fr. Joseph Terfa Beba, the NCDPA expressed concern over what it described as the apparent exclusion of the Benue State Government from the decision-making and approval process.
The association said had the elected leadership of Benue State been genuinely consulted, it believed the state government would not have consented to any arrangement capable of undermining the rights, dignity, security and ancestral heritage of its people.
“We cannot accept a policy imposed upon a people whose communities have suffered killings, displacement, destruction and prolonged insecurity,” the association said.
It warned that ranching must not become a disguised instrument for land grabbing, forced occupation or the permanent displacement of indigenous communities.
The priests also cited the position of the Catholic Bishop of Makurdi Diocese, Bishop Wilfred Chikpa Anagbe, CMF, saying he had “consistently and courageously spoken against this injustice, culpable silence and every agenda that threatens the ancestral lands of our people.”
The association called on the Federal Government to respect the constitutional rights of the people of Benue State and engage the state government, traditional rulers and community leaders transparently before proceeding with the policy.
It also urged the government to ensure that displaced persons are enabled to return safely and take possession of their ancestral lands before any discussions concerning already existing designated ranching structures in parts of the state and the country.
The NCDPA maintained that Benue was predominantly an agrarian state and not a pastoralist society, arguing that ranching was therefore not viable in the state.
“Ranching in Benue State is therefore NOT VIABLE, and WE REJECT THIS PROJECT IDEA WITH ALL LEGAL AND SPIRITUAL RESOURCES,” the priests declared.
The association said there was no land in Benue for commercial ranching, stressing that ancestral homes should not be treated as bargaining chips.
“Our land is not for sale and has never been on sale. There is no land in Benue State for commercial ranching. Our ancestral homes are not bargaining chips.
“Our people must return home. Benue must not be enslaved through policy. There will be no surrender of our ancestral heritage in whatever form or guise being proposed or presented,” it said.
The association urged the Federal Government to address the concerns of Benue communities and prioritise the safe return of displaced persons before implementing any ranching arrangement in the state.

Stephen Olufemi Oni, Ilorin

A fresh initiative aimed at preserving the legacy of service, compassion and grassroots development associated with the late former Oyo State Governor, Otunba Christopher Adebayo Alao-Akala, has been launched with the inauguration of the Alao-Akala Transformation Movement (ATM).

The movement, chaired by the late governor’s wife, Chief (Mrs.) Oluwakemi Alao-Akala, has been formally inaugurated in Ogbomoso as part of activities marking the posthumous celebration of the former governor, who died in 2022.

Speaking at the event, Oluwakemi said ATM was established to transform Alao-Akala’s philosophy of leadership and philanthropy into sustainable programmes capable of improving the lives of people across communities.

“This is not merely the inauguration of an organisation; it is the birth of a movement inspired by service, compassion, integrity and selfless leadership,” she said.

She stressed that ATM was neither a political party nor a partisan platform, noting that membership was open to people irrespective of political affiliation, ethnicity or religious background.

“Service to humanity knows no political boundary,” she declared.

According to her, the movement emerged after months of consultations involving members of the Alao-Akala family, political associates, community leaders, professionals, youths and admirers of the late governor.

She disclosed that the inaugural planning meeting was held at the family residence in Ibadan in March 2026, with subsequent meetings taking place every Tuesday at the movement’s headquarters.

Oluwakemi, who disclosed that ATM had already attracted members from the 33 local government areas of Oyo State, other parts of Nigeria and the Diaspora, explained that one of the movement’s major priorities was to sustain and expand Alao-Akala’s philanthropic legacy through interventions targeting widows, vulnerable families, students and other less privileged members of society.

“By the grace of God, we shall continue to deepen these interventions while introducing new initiatives in youth empowerment, educational support, healthcare, community development, leadership mentoring and social welfare,” she said.

The ATM chairperson appealed to individuals, corporate organisations, development partners and other well-meaning Nigerians to support the movement financially, professionally and through volunteer services.

She said the objective was to ensure that Alao-Akala’s legacy did not remain confined to speeches and annual commemorations but was translated into practical interventions that would positively affect communities.

As part of activities preceding the inauguration, members of ATM visited the Adebayo Alao-Akala College of Health Sciences in Ogbomoso and the Adebayo Alao-Akala Comprehensive Health Centre in Yaku Community.

Oluwakemi said the visits underscored the movement’s commitment to preserving the late governor’s contributions to healthcare, education and rural development.

She also explained the postponement of the inauguration, which was originally scheduled for June 3, 2026.

According to her, the event was postponed following the abduction of teachers and schoolchildren in Yawota and Esin Ele communities in Oriire Local Government Area.

“We considered it inappropriate to celebrate while families were in distress,” she said.

She expressed appreciation to President Bola Ahmed Tinubu, Governor Seyi Makinde, the Armed Forces, Nigeria Police Force, Department of State Services, Nigeria Security and Civil Defence Corps, local security volunteers and other agencies for their roles in securing the release of the abducted victims.

She also honoured security personnel who lost their lives during the rescue operation, praying for the repose of their souls and strength for their bereaved families.

The inauguration attracted political leaders, traditional rulers, religious leaders, members of the Alao-Akala family, supporters and representatives from across Oyo State.

Among those present were Senator Sharafadeen Alli, the All Progressives Congress governorship candidate for the 2027 election in Oyo State; his running mate, Hon. Michael Adesoye; and the Soun of Ogbomosoland, Oba Ghandi Afolabi Olaoye, Orumogege III, among other dignitaries.

Born on June 3, 1950, in Ogbomoso, Alao-Akala began his career in the Nigeria Police Force before venturing into politics.

He served as Chairman of Ogbomoso North Local Government, Deputy Governor of Oyo State and later Governor of the state.

His administration was associated with projects in road infrastructure, education, healthcare, rural development, agriculture, youth empowerment and security.

His name remains particularly associated with the Adebayo Alao-Akala College of Health Sciences in Ogbomoso and the Adebayo Alao-Akala Comprehensive Health Centre in Yaku Community.

Beyond political office, he was also known for philanthropy, with interventions reaching widows, students, artisans, traditional institutions, religious organisations, youth groups and other vulnerable members of society.

Oluwakemi said ATM provided an avenue for the family and admirers of the late governor to ensure that his values continued to inspire younger generations.

“The Alao-Akala Transformation Movement belongs to everyone who believes in compassionate leadership, peaceful coexistence and sustainable development,” she said.

“Together, we shall preserve a worthy legacy and transform lives for generations yet unborn.”

The inauguration also featured the presentation of a documentary titled “Otunba Christopher Adebayo Alao-Akala: A Legacy of Service”, goodwill messages from representatives of the Alao-Akala family, traditional rulers, political associates, friends and well-wishers, as well as a message from the Oyo State Government.

The vision, mission and objectives of ATM were formally presented by Mr Ademola Alao-Akala, while Hon. Olamiju Alao-Akala, MHR, delivered the vote of thanks.

Oluwakemi urged members and supporters to remain committed to the ideals of the movement, stressing that its ultimate goal was to turn Alao-Akala’s record of service into sustained humanitarian and developmental interventions.

“Akala Ni Joo, ATM! Akala Ni Jare, ATM! Ise Rere ’O Dura,” she declared.
