Keynote Title: Maps that Think, Services that Understand: A Cartographic Vision for the Future of Location-Based Services

Abstract: Location-Based Services are rapidly evolving from navigation and information retrieval tools into intelligent systems capable of understanding users, context, and place. Powered by GeoAI, future LBS will not only answer where questions but also support spatial reasoning, explain alternatives, communicate uncertainty, and anticipate user needs. This keynote argues that achieving this vision requires more than advances in artificial intelligence—it requires cartography. By providing principles for abstraction, context, communication, and human-centred design, cartography offers the conceptual foundation for trustworthy, explainable, and adaptive GeoAI. The keynote presents a vision of maps as intelligent interfaces that connect people, places, and AI, enabling the next generation of Location-Based Services to become true spatial intelligence systems.

Biography: Georg Gartner is Full Professor of Cartography at TU Wien (Vienna University of Technology), Austria, and President of the International Cartographic Association (ICA). His research focuses on the conceptual foundations of cartography, Location-Based Services, spatial cognition, and the integration of GeoAI into next-generation spatial intelligence systems. He has authored over 300 scientific publications and has led numerous international research and educational initiatives in cartography. In recognition of his contributions, he has received numerous awards and honours. These include Honorary Doctorates from Eötvös Loránd University (Budapest), the ICA Honorary Fellowship, and an Honorary Professorship from the Chinese Academy of Surveying and Mapping. He serves currently as Vice-Chair of the UN-GGIM Academic Network.

Keynote Title: Handling Uncertainties in Location-Based Service

Abstract: Reliable location-based services require spatial data that are accurate, current, and fit for purpose. However, uncertainties introduced during data acquisition, integration, analysis, and updating can propagate through the service workflow and affect the reliability of its outputs. This presentation introduces an uncertainty-aware framework that connects mobile mapping, spatial data infrastructure, and location-based services. Mobile mapping systems integrate positioning, imaging, LiDAR, and other sensing technologies to provide high-precision and continuously updateable spatial data. The resulting data are organised within a spatial data infrastructure, where their quality and uncertainties can be assessed, communicated, and controlled before use by location-based applications. The framework is demonstrated through defect detection, Scan-to-BIM, and infrastructure monitoring. These examples show how spatial observations can be linked to detected objects, risks, and service decisions within a consistent reference framework while accounting for uncertainty throughout the workflow. By integrating uncertainty handling from mobile data acquisition to service delivery, the approach supports more reliable, explainable, and safety-aware location-based services.

Keynote Title: Transforming LBS to Spatial Intelligence by Embodied Navigation

Abstract: Enabled by the rapid development of artificial intelligent technologies, Location-Based Service (LBS) is now transforming to spatial intelligence. Embodied navigation is a key technology powering this transition. This speech will present a few potential localization technologies that will be adopted in a robot platform to form an embodied navigation solution. Furthermore, a cooperative positioning solution engaging with smartphones and robots will be introduced. The speech will be concluded with various applications of spatial intelligence.

Biography: Dr. Ruizhi Chen is Professor of the Chinese University of Hong Kong, Shenzhen. He is a member of the Finnish Academy of Science and Letters. He has developed indoor positioning technologies for smartphones and wearable devices, including the World’s first indoor positioning solution using Electromyography (EMG) sensor; a commercialized technology called Acoustic Positioning System, which has received two rounds of VC investments. He led a team that won the grand challenge in indoor positioning in 2018 organized by NIST in US. His research results were published as cover stories twice in GPS World. He has published 2 books and more than 240 SCI papers cited by 13129 times in Google Scholar with an H-index of 60. He has received 38 Chinese patents and 6 US patents.

Keynote Title: ‘Location’ in Location-based Services

Abstract: The term 'location' lacks a clear conceptualization both in the broader context of common language and in the domain of technology. In my talk I will line out the parallels to Kuhn’s core concepts of spatial information, discuss these interpretations, and how the term is useful but also limited in these multiple interpretations. I will illustrate the different uses of the term in applications relevant to location-based services.

Biography: Stephan Winter is Professor of Geospatial Information Science at the University of Melbourne’s Department of Infrastructure Engineering. His research applies spatial cognition principles to develop intelligent systems for indoor/outdoor navigation, wayfinding, and transport. He also contributes to engineering education research. He publishes broadly, across geospatial science, computing, and transportation engineering venues. He serves on the ISPRS International Scientific Advisory Committee and steering committees for COSIT and GIScience. He is member of the IEEE ITS Society and ACM SIGSPATIAL
