Indoor/Outdoor Seamless Modelling, LBS and Mobility

Our Mission

ISPRS Working group IV/5 aims to promote research on indoor/outdoor seamless reality modelling, location based services (LBS), tracking, monitoring 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 semantic description of indoor/outdoor (including underground) seamless environments (e.g. BIM, CityGML, GML 3) for location based services, public security and disaster management. Besides, the WG also stimulates mobility research, using latest tracking, monitoring, and data mining algorithms, for different application areas, e.g., routing, traffic monitoring, evacuation, disabled/aged care, etc.

To facilitate this, the WG organises workshops and special issues to exchange the latest developments and form scientific vision on indoor/outdoor seamless modelling, LBS and mobility. Furthermore the WG will provide a set of benchmark semantic model and movement datasets, and organise international comparative tests on the performance of algorithms for LBS and mobility.

Finally, networking will be in the heart 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 indoor/outdoor seamless environment modelling and movement analysis.
