Meiliu as Invited Speaker at National University of Singapore, Feb 16, 2025

Huge thanks to Filip Biljecki and Wei Luo! It was truly an engaging and enjoyable experience to visit NUS Urban Analytics Lab. 😊

As AI advances, the fusion of multimodal data (e.g., images, text, and spatial information) unlocks unprecedented opportunities for geospatial understanding. This talk introduces an innovative GeoAI framework that extracts and integrates spatial knowledge using Vision-Language Models (VLMs), including GPT-4 and Contrastive Language-Image Pretraining (CLIP), to enhance geospatial analytics. By enabling AI to interpret both visual and linguistic data with spatial awareness, this work expands the capabilities of AI to tackle complex geospatial tasks, such as image geo-localization, land use detection, and urban perception prediction. The core of this framework leverages spatially explicit prompt engineering and contrastive learning, refining AI models to reason about geo-locations and spatial patterns. These techniques set a new benchmark for AI in geospatial applications, offering scalable, accurate, and explainable insights across diverse environments. As we push the boundaries of GeoAI, the integration of VLMs and spatial reasoning is paving the way for more intelligent, interpretable, and impactful decision-making in the geospatial domain and beyond.
