Defining a Model for Integrating Indoor and Outdoor Network Data to Support Seamless Navigation Applications

open access: yesISPRS International Journal of Geo-Information, 2021
Spaces are continuous realms where human beings freely navigate, such as from indoor to outdoor and optionally to another indoor space. However, currently available data models to represent space for navigation do not entirely reflect this continuity of ...
