The increasing use of location-aware devices has led to an increasing availability of
trajectory data. As a result, researchers devoted their efforts to developing analysis methods …

This paper surveys indoor spatial models developed for research fields ranging from mobile
robot mapping, to indoor location-based services (LBS), and most recently to context-aware …

This paper begins by reviewing the motivation for an informatics of indoor space. It then
discusses application domains and consider why current geospatial technology, with its …

As we realize that we spend most of our time in increasingly complex indoor environments,
applications to assist indoor activities (eg guidance) have gained a lot of attention in the …

In spatial science and urban applications,“space" is presented by multiple disciplines as a
notion referencing our living environment. Space is used as a general term to help …

Contemporary public buildings are becoming conglomerates of open, semi‐open and
closed spaces, with indoor, outdoor and underground sections. For humans and robots to …

Abstract 3D indoor navigation in multi‐story buildings and under changing environments is
still difficult to perform. 3D models of buildings are commonly not available or outdated. 3D …

In this paper, we describe an infrastructure-independent indoor localization approach for
various indoor environments. Our method introduces a novel particle filter implementation …

Navigation systems help agents find the right (optimal) path from the origin to the desired
destination. Current navigation systems mainly offer the shortest (distance or time) path as …

Continuous location-dependent queries are key elements for the development of location-
based and context-aware services. While most work on location-dependent query …
