KEYNOTE SPEAKER TALK – INTERNATIONAL CONFERENCE ON WATER, ENVIRONMENT, ENERGY AND SOCIETY (ICWEES 2025)

Keynote Abstract:

The keynote by Associate Professor Uznir Ujang explores the transformative potential of integrating 3D Geospatial Information Systems (3D GIS) with Geospatial Artificial Intelligence (GeoAI) for tackling urban challenges related to environmental quality, water systems, and energy efficiency. Traditional 2D geospatial methods often fall short in capturing the complexities of urban dynamics. This talk introduces a new paradigm where advanced 3D city models, enhanced by AI-driven spatial analytics, topological structures, and temporal intelligence, offer innovative solutions for resilient city planning.

Key real-world case studies, such as urban air quality visualization, traffic noise propagation, wind flow analysis, and voxel-based environmental simulations, demonstrate how this convergence of technologies can revolutionize decision-making. With data acquisition methods like LiDAR, UAVs, and CityGML semantic modeling, cities can leverage precise, intelligent tools to address sustainability challenges.

Join us as we discuss the future of integrating 3D geospatial intelligence into global sustainability frameworks and urban agendas.

CONGRATULATIONS TO ABDULLAH AHMAD (UKM)

CONGRATULATIONS TO ABDULLAH AHMAD

Warm congratulations to Abdullah bin Ahmad (P127080) from the Department of Civil Engineering, UKM, for successfully completing his Master of Science viva voce! He is a senior engineer at the Public Works Department (JKR). 

His thesis focused on a highly relevant topic: GeoBIM Data Structure for Sewer System, which I believe is a crucial area in advancing infrastructure management through geospatial and BIM integration. From my view, the nation needs more awareness on the importance of GeoBIM. It is good to have more research like Abdullah’s. 

The session was held on 14 April 2025 (Monday), at 9:30 a.m. at the Faculty of Engineering and Built Environment, UKM Bangi.

I was honored to serve as the External Examiner, representing Universiti Teknologi Malaysia (UTM).

The viva panel included:

Chairperson: Prof. Ir. Dr. Siti Rozaimah Sheikh Abdullah (JKKP, FKAB)

Internal Examiner: Sr. Ts. Dr. Noraini Hamzah (JKA, FKAB)

Main Supervisor: Lt. Kol. Bersekutu (PA) Prof. Madya Ts. Gs. Sr. Dr. Khairul Nizam Abdul Maulud (JKA, FKAB)

Thank you to Universiti Kebangsaan Malaysia (UKM) for the trust and opportunity. It’s always a privilege to contribute to academic quality and support innovative research through external examiner roles.

Wishing the candidate every success in future research and practice!

KEYNOTE TALK: GEOAI-DRIVEN 3D URBAN MODELLING

KEYNOTE TALK: GEOAI-DRIVEN 3D URBAN MODELLING

It’s an honour to be given a 45-minute keynote slot, an academic recognition that reflects trust from the international scientific community. 

Unlike typical paper presentations, a keynote isn’t just about showing results. It’s about vision. Future directions. Inspiring researchers across disciplines.

Sharing how Geospatial Science matters, whether it’s for noise modelling, wind flow, water systems, or urban resilience. This keynote is my way of showing how 3D City Modelling and GeoAI can drive meaningful applications across sectors.

Just an abstract for today. The rest of the presentation notes will be drafted later.

BOOK CHAPTER COMPLETED! AVOID MULTITASKING.

Book Chapter Completed! Avoid Multitasking.

Pushing limits, one chapter at a time! Just wrapped up a 27-page book chapter with 51 citations and 10,000 words—all within 12 hours while juggling daily responsibilities. As a solo writer.

Not my fastest work—used to complete similar chapters in just 6 hours over — but this one tested my endurance.

It’s a reminder that consistency and practice are key to keeping skills sharp. Avoid multitasking. It will not benefit you in the long run. Learn from other civilizations.

Every challenge is an opportunity to improve, and this was no exception. On to the next one!

UNEXPECTED REUNION AT 30,000 FEET

Guess who I met today! 🙂 Erin, one of my former academic advisees. The last time we met was in 2019 when she came to my office to get my signature on her graduation form. Her final question to me was, “Dr., do you think I should continue in GIS or become a stewardess?”. Without hesitation, I answered, “Stewardess”. If my ex-boss (pensioned) knew, they’d probably be mad at me, since I was supposed to encourage her to stay in GIS. But as her academic advisor, I knew Erin personality very well.

Today, I’m so happy to see her thriving. I always wished to bump into her on a flight, but we kept seeing each other from far away at the airport, until today, when we finally ended up on the same flight. Erin even met her soulmate at work, and I got to meet her husband today! Before this, I only saw him in her stories.

Also, I’ve never received a gift on an AirAsia flight (because, well, it’s AirAsia right), but today was a first! My son got a cool AirAsia toy, and we received drinks. Thank you, Erin and your husband. As your academic advisor, I’m so proud of you. Even though you’re now a mother, I still see you as the same bright and youthful Erin from your first year.

GREEN BELTS IN 3D – A NATURAL SOLUTION FOR TRAFFIC NOISE MITIGATION

GREEN BELTS IN 3D – A NATURAL SOLUTION FOR TRAFFIC NOISE MITIGATION

This is our latest publication titled “Traffic Noise Absorption and Propagation in a Three-Dimensional Spatial Environment” in Geoplanning: Journal of Geomatics and Planning.

This research explores the role of tree canopies as noise barriers using advanced LiDAR-based 3D models. By visualizing tree structures in 3D, we analyzed their noise absorption performance and identified how green belts can effectively reduce traffic noise propagation.

Okay the Key Findings:

-Tree leaves play a major role in absorbing noise.

-3D Convex Hull and Concave Hull methods improve canopy surface estimation.

-Voxel-based models provide better accuracy for leaf surface area and density analysis.

The study emphasizes the potential of green belts as cost-effective and sustainable noise mitigation solutions, particularly for developing countries.

Imagine quieter roads and healthier urban environments that is powered by nature and technology.
