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.

PHD VIVA VOCE

PHD VIVA VOCE

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.

4TH CHAPTER COMPLETED – 4 CHAPTERS IN 2 WEEKS

4TH CHAPTER COMPLETED – 4 CHAPTERS IN 2 WEEKS

Finally, it’s a wrap! Chapter 4 is done, 5,800 words, 16 pages, and 40 references, completed in just 6 hours. Had to put it on hold on Wednesday, but today I squeezed in 1.5 hours to finish it strong.

This marks a major milestone, 4 book chapters completed in just 2 weeks. It wasn’t easy, but persistence and time management made it happen. One key takeaway: avoid multitasking, focus leads to faster and better results.

Every chapter is a challenge, and every challenge is a step forward. Alhamdulillah for the progress. Now, on to the next one!

ANOTHER RESEARCH ARTICLE

ANOTHER RESEARCH ARTICLE

Got another journal article for 2025. It’s indexed in the Web of Science and even has a quartile ranking, which is quite decent.

Despite my daily workload and other responsibilities, I make it a priority to write and publish my own journal articles. Lately, I’ve noticed a trend where lecturers rely heavily on students to write journals, and worse, the lecturers end up as the main authors (first in the author name list). It should be the other way around, the students should rely on the supervisor for journal writing.

It’s undeniable that lecturers’ responsibilities are demanding, but academic writing is something that should be done by lecturers themselves, no matter how busy we are.

This journal will take a while to be officially published, scheduled for July 2025, but it’s a strong start to the year. With two high-impact research publications in January 2025, I couldn’t be more grateful.

Stay tuned for the article in July!

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.

STRENGTHENING RESEARCH SKILLS: SYSTEMATIC LITERATURE REVIEW (SLR) TRAINING

STRENGTHENING RESEARCH SKILLS: SYSTEMATIC LITERATURE REVIEW (SLR) TRAINING

On Sunday, we kicked off Day 1 of the Systematic Literature Review (SLR) training session, a personal coaching initiative for my research group. This effort is dedicated to enhancing the research capabilities of my postgraduate students and lab members.

The session, conducted by our very own Lab 3D PhD student, Hafiz Usman Mehmood. He has a vast experience writing this type of paper. Our day 1 training covered critical aspects of SLR, including:

1. Introduction to SLR

2. Importance in Academic Research

3. Developing Research Questions

4. Selecting Databases & Searching Articles

5. Screening & Applying Inclusion/Exclusion Criteria

I believe that empowering young researchers with structured approaches like SLR is key to producing impactful, high-quality research.

These closed training sessions reflect our commitment to cultivating a strong research foundation within our lab. Tomorrow, we move to Day 2 with advanced topics, including the PRISMA framework and qualitative synthesis.
