| Summary : Top-Down Time Ratio Segmentation for Coordinate Trajectories
|
Description :
Data collected on movement behavior is often in the form of time-
stamped latitude/longitude coordinates sampled from the underlying
movement behavior. These data can be compressed into a set of segments
via the Top- Down Time Ratio Segmentation method described in Meratnia
and de By (2004) < doi:10.1007/978-3-540-24741-8_44> which, with some
loss of information, can both reduce the size of the data as well as
provide corrective smoothing mechanisms to help reduce the impact of
measurement error. This is an improvement on the well-known
Douglas-Peucker algorithm for segmentation that operates not on the
basis of perpendicular distances. Top-Down Time Ratio segmentation
allows for disparate sampling time intervals by calculating the
distance between locations and segments with respect to time. Provided
a trajectory with timestamps, tdtr() returns a set of straight- line
segments that can represent the full trajectory. McCool, Lugtig, and
Schouten (2022) < doi:10.1007/s11116-022-10328-2> describe this method
as implemented here in more detail.
