Summary
This talk will delve into the evolving journey and vision of using space-time data to deliver societal benefits, transitioning from integrated spatiotemporal modelling to network and graph-based deep learning, and ultimately to generative GeoAI for urban studies. It will highlight the benefits of adopting an integrated space-time and network-based structure as a versatile spatial framework for representing complex processes traditionally illustrated by points, polylines, and polygons. We propose the utilisation of multi-layered networks and graph databases as the foundation for urban digital twins and Urban (Geo) Foundational Models. The presentation will feature applications of network and graph-based SpaceTimeAI, including graph-based deep learning for predictive modelling, space-time clustering, optimisation, and transformer-based data fusion. The demonstrated applications span multiple domains, such as transport and mobility, crime and policing, and public health.
