The discovery of regions of interest in large cities is an important challenge. We propose and
investigate a novel query called the path nearby cluster (PNC) query that finds regions of …

Indoor spaces accommodate large numbers of spatial objects, eg, points of interest (POIs),
and moving populations. A variety of services, eg, location-based services and security …

ABSTRACT A large proportion of indoor spatial data is generated by parsing floor plans.
However, a mature and automatic solution for generating high-quality building elements (eg …

Indoor spaces accommodate large parts of people's life. The increasing availability of indoor
positioning, driven by technologies like Wi-Fi, RFID, and Bluetooth, enables a variety of …

In the past decade, positioning system-enabled devices such as smartphones have become
most prevalent. This functionality brings the increasing popularity of location-based services …

Much research has been conducted on the management of outdoor moving objects. In
contrast, relatively little research has been conducted on indoor moving objects. The indoor …
