The processes that cause and influence movement are one of the main points of enquiry in
movement ecology. However, ecology is not the only discipline interested in movement: a …

The Handbook of Discrete and Computational Geometry is intended as a reference book
fully accessible to nonspecialists as well as specialists, covering all major aspects of both …

With the rapid development of urban transportation, people urgently need high-precision
and up-to-date road maps. At the same time, people themselves are an important source of …

We present an algorithmic framework for criteria-based segmentation of trajectories that can
efficiently process a large class of criteria. Criteria-based segmentation is the problem of …

The ubiquity and variety of available sensors has enabled the collection of voluminous
datasets of car trajectories that enable analysts to make sense of driving patterns and …

We describe an online algorithm to simplify large volumes of location and sensor data on the
source mobile device, by eliminating redundant data points and saving important ones. Our …

With the rapid development of internet economy, transparent logistics is stepping into a
prosperity period with massive transportation data generated and collected every day. In this …

Segmentation techniques partition a sequence of data points into a series of disjoint
subsequences—segments—based on some criteria. Depending on the context and the …

We study one of the basic tasks in moving object analysis, namely the location of hotspots. A
hotspot is a (small) region in which an entity spends a significant amount of time. Finding …

We present a framework for the partitioning of a spatial trajectory in a sequence of segments
based on spatial density and temporal criteria. The result is a set of temporally separated …
