With the rapid development of mobile data acquisition technology, the volume of available
spatial data is growing at an increasingly fast pace. The real-time processing of big spatial …

Motivated by the trend of providing comprehensive knowledge about trajectory data, we
study multi-attribute trajectories each of which contains a sequence of time-stamped …

The range query is one of the most important query types in spatial data processing.
Geographic information systems use it to find spatial objects within a user-specified range …

We study multi-attribute trajectories by combining standard trajectories (ie, a sequence of
timestamped locations) and descriptive attributes. A new form of continuous k nearest …

With continued development of location-based systems, large amounts of trajectories
become available which record moving objects' locations across time. If the trajectories …

Due to the COVID-19 pandemic, numerous workplaces, organisations, and public venues
closed their doors. Recently, many have reopened under social distancing restrictions …

Current moving-object database (MOD) systems focus on management of movement data,
but pay less attention to modelling social relationships between moving objects and spatial …

The rapid growth of location-based services has motivated the development of continuous
range queries in networks. Existing query algorithms usually adopt an expansion tree to …

In this article, we survey the main achievements of moving objects with transportation modes
that span the past decade. As an important kind of human behavior, transportation modes …

Existing data models for moving objects in networks are often limited by flexibly controlling
the granularity of representing networks and the cost of location updates and do not …
