Title: GeoAI and 3D Urban Modelling: Revolutionizing Surveying and Geoinformation for Sustainable Cities

Abstract:

The rapid pace of urbanization has introduced complex challenges in environmental monitoring, infrastructure planning, and sustainable development. Traditional 2D surveying and geoinformation systems are increasingly limited in addressing these multidimensional issues. This keynote introduces a transformative approach, integrating Geospatial Artificial Intelligence (GeoAI) with 3D urban modelling, to advance the capabilities of surveying and geoinformation science. We will explore how data from UAVs, LiDAR, and satellite imagery can be combined with 3D GIS standards (e.g., CityGML, IFC) and AI techniques (e.g., deep learning, spatial clustering) to create dynamic, predictive urban models. Applications will include air pollution mapping, noise propagation analysis, wind comfort simulation, and energy efficiency optimization in city environments. This talk emphasizes the critical role of interoperability, spatial reasoning, and automation in modern surveying workflows. The outcomes not only support smarter city planning but also align directly with Sustainable Development Goals (SDGs), particularly SDG 11 (Sustainable Cities) and SDG 13 (Climate Action). By bridging GeoAI with 3D modelling, we unlock a powerful spatial paradigm that redefines how we survey, analyze, and design the cities of tomorrow.
