Digital Twins for Mobility and Navigation

Our Mission

Based on realistic indoor/outdoor environment modelling, ISPRS Working group IV/8 aims to promote research on Digital Twin-based navigation, location based services (LBS) and mobility. Differing from the spatial aspect which has been well addressed in the communities of Sensor Systems and Photogrammetry, this WG focuses on the developments of state-of-the-art algorithms and semantic and topological models for modelling indoor/outdoor (including underground) environments. Besides, the WG also stimulates mobility research, using latest tracking and data mining algorithms for different application areas (e.g., traffic monitoring, behavioural control, etc.), navigation research using state-of-the-art positioning techniques for application communities (e.g., way-finding, evacuation, etc.), and LBS research for application fields (e.g., disabled/aged care, contextualized content delivery, etc.).

To facilitate this, the WG organises workshops and special issues to exchange the latest developments and build scientific vision on digital twins for navigation, LBS and mobility. Furthermore, the WG will provide publicly available multimodal benchmark datasets for evaluating multiple tasks (e.g., semantic, topological, etc.), and organise international comparative tests on the performance of algorithms for navigation, LBS and mobility analysis.

Finally, networking will be in the core of the activities of the working group members from around the world. The WG will collaborate closely with other ISPRS working groups, particularly in Commissions I and II, and will cooperate with OGC and other international groups to promote and contribute to the advance of knowledge and innovation in relation to digital twins for navigation, LBS and mobility.
