SOUNDSCAPES UNVEILED: ADVANCEMENTS IN 3D CITY MODELLING FOR 3D TRAFFIC NOISE VISUALIZATION 

Excited to share our latest publication in the Geomatics and Environmental Engineering journal: “Calculation of Road Traffic Noise, Development of Data, and Spatial Interpolations for Traffic Noise Visualization in Three-dimensional Space.”

Our study delves into the essentials of 3D traffic noise visualization, emphasizing the critical role of noise observation points (NOPs) and advancements in spatial interpolations. Explore how TIN noise contours prove optimal for visualizing traffic noise levels, and how advanced kriging, such as empirical Bayesian kriging (EBK), provides a significant leap in 3D noise interpolation accuracy.

BREAKING BOUNDARIES: A DEEP DIVE INTO 3D CITY MODELLING TOPOLOGY RULES IN GIS APPLICATIONS

Thrilled to share insights from our groundbreaking research: “Topology Models and Rules: A 3D Spatial Database Approach”. Our study delves into the intricate world of topological information, crucial for complex spatial analysis, particularly in describing the containment, adjacency, and connectivity of objects within a 3D space.

Traditionally, spatial databases have leaned on 2D topology mechanisms, often falling short in handling the intricacies of 3D topology functions. Our experiments, conducted within ArcGIS and Oracle spatial database, unveil the limitations of existing topology rules and models. Notably, while 2D geodatabase topology rules in ArcGIS effectively determine relationships between 2D multi-surfaces, they struggle with 3D objects.

Enter the 36-Intersection Model (36IM), the hero of our study. This innovative model, describing intersections from 0D to 3D, introduces a paradigm shift in handling topological relationships within Oracle. Our experiments showcase how 36IM topology rules bridge the gap, providing insights into dimensions of intersections and supporting the maintenance of topological information without breaking down 3D objects.

Curious to dive deeper into the world of 3D GIS, spatial databases, and the nuances of topology models? Explore our full paper for a comprehensive understanding of how 3D topology rules reshape the landscape of spatial data management. Elevate your knowledge and stay ahead in the evolving realm of GIS and 3D spatial databases!

UNLOCKING URBAN SPACES: A 3D SPATIAL ANALYSIS OF TEMPORAL MAINTENANCE IN MULTI-USE HIGH-RISE BUILDINGS

Exciting news to share! Kudos to my PhD students, Usman and Syahiirah, for the publication of their joint paper in the Geomatics and Environmental Engineering journal – a Scopus Q3 indexed publication. Our paper, titled “3D Spatial Analysis of Temporal Maintenance for Multi-use High-rise Buildings: Case Study,” delves into the complexities of managing and maintaining spaces in high-rise buildings amidst urbanization.

Summary: The study focuses on implementing temporal maintenance management for high-rise building parcels within a 3D spatial database. It involves 3D space segmentation to analyze ownership and usage, spatial queries for temporal maintenance, and 3D spatial relationships to identify adjacent parcels affected by maintenance. This innovative approach ensures accurate representation and identification of spaces crucial for enhancing the quality of life in multi-use high-rise buildings.

BIG DATA SPATIAL MODELS FOR TEMPORAL GRAPH DATABASES SPATIAL QUERIES

Exciting news! Our recent IEEE publication, “Modelling Reoccurrence of Events in an Event-Based Graph Database for Asset Management,” explores efficient ways to handle recurring maintenance events in asset management.

We introduce three temporal graph data models, assessing their performance on synthetic datasets. The findings highlight the second model’s efficiency with smaller datasets and the third model’s prowess with big data scenarios.

These models go beyond asset management, providing a foundation for event-based data management using graph databases. Dive into the full paper for insights into optimizing asset maintenance and more!

Flavors of Success – A BBQ Night with the Dream Team

Had an amazing BBQ night with my wonderful postdoctoral, PhD, and MPhil students at Sireh Park, right by the lake. We enjoyed delicious BBQ and skewers, sipped on chai from Usman, savored the fantastic sauce from Husna, indulged in viral drinks by Farah, and were treated to expert grilling by Nevil and Tariq.

It was also our first research lab outdoor activity with our newly registered MPhil student, Wiliyan Ricky Abdullah. Exciting times ahead! 

And a warm welcome to Dr. Khaled Almansi as well, our new postdoctoral staff from Palestine, who just arrived today and BBQ night is his first activity with us. Looking forward to a couple of years of research experiments in 3D City Modelling and GIS with him. 

I did not know that my students are talented in F&B business as well. Thank you for making this night fantastic #TeamWork #ResearchNight #BBQFun

Fun times at Usman’s place!
